Elasticsearch is a great product!
Elasticsearch is being used to store and search architecture standards, guidance, and other documents pertaining to software architectures. When used with the Spring Java Framework, it is extremely easy to set up custom queries.
- Search queries based on Java class member names.
- Very detailed queries through the standard library.
- Extremely fast.
- Easy to index.
- Ability to search content when data only in fields.
- Query syntax could be made simpler.
- Auto sharding.

Reliable and affordable solution which is figuring as a industry pattern for managing huge data searching.
In a cloud universe where we have hundreds or even thousand of servers to manage, is is a huge challenge to figure out the root cause of issues, it is totally unacceptable keep this sort of environment without a reliable logging and analysis system. Being part of the ELK stack, Elasticsearch give us what is necessary to handle this huge amount of data. I can't imagine our environments without Elasticsearch nowadays.
- Centralized logging
- Easy content searching
- Handle tons of data
- Poor documentation
- Not so easy at the first contact
- Hard to debugging issues

Very useful for eCommerce
Elasticsearch is used on our B2B and B2C eCommerce websites to provide fast and powerful search capabilities for products. Search by title, artist, or various facets like genre, price-range and availability-date results in a list of products that the user can then drill down or continue searching within the result list. Within the organization, Elasticsearch is used by the programmers in the IT department.
- Search results are provided very quickly.
- The search results are accurate.
- Search results contain details on the accuracy of each hit.
- There is a steep learning curve for this product so what is most useful for developers is good documentation including examples and sample applications.

Elasticsearch is the future!
The most crucial piece of infrastructure behind my company's whole product line is Elasticsearch. Our company's big selling point is an extremely flexible data model for our customers who send us their data. We want them to be able to send us data in almost whatever shape or form they want (as long as it's valid JSON we'll take it) and yet, make it still searchable. And you know how we store that nearly-unrestricted free-form data? Elasticsearch!
- As I mentioned before, Elasticsearch's flexible data model is unparalleled. You can nest fields as deeply as you want, have as many fields as you want, but whatever you want in those fields (as long as it stays the same type), and all of it will be searchable and you don't need to even declare a schema beforehand!
- Elastic, the company behind Elasticsearch, is super strong financially and they have a great team of devs and product managers working on Elasticsearch. When I first started using ES 3 years ago, I was 90% impressed and knew it would be a good fit. 3 years later, I am 200% impressed and blown away by how far it has come and gotten even better. If there are features that are missing or you don't think it's fast enough right now, I bet it'll be suitable next year because the team behind it is so dang fast!
- Elasticsearch is really, really stable. It takes a lot to bring down a cluster. It's self-balancing algorithms, leader-election system, self-healing properties are state of the art. We've never seen network failures or hard-drive corruption or CPU bugs bring down an ES cluster.
- Elasticsearch paid support could be much better. Not only is it really expensive, but the reps just don't seem to be that knowledgeable and keep linking us to support documentation we've already found and read.
- I wouldn't call it missing functionality or a part that's hard to use perse, but upgrading from ES 5 to ES 6 is a PITA. Maaaan did they mess up a part of their data model so bad that when migrating, you have to restructure almost all your queries and transform almost all your data! I don't want to go into too many details here as some people may not be clued in on the concept of mapping types, but you can read more about it here https://www.elastic.co/guide/en/elasticsearch/reference/6.0/breaking-changes-6.0.html.
- This is no longer a problem in ES 6 but in versions 5 and before, reindexing is a PITA. You have to almost bring down the whole cluster to fix small problems such as missing fields or wrong types.

Win quickly with Elasticsearch
Elasticsearch is used as a full-text search solution in most of my use cases. We have another analytics us -case which uses Elasticsearch for both text search and aggregation use-cases.
- Extremely easy to get started and great documentation.
- Excellent for full-text use cases.
- Also used for analytics and Kibana UX is great for visualization.
- Encountered scaling challenges with large data sets (typically in petabytes).
- Performance issues for raw aggregation use-cases.
- Every contract (request/response) is in JSON which is not optimal. No support for protobuffs or GRPC.
Elasticsearch has been phenomenal in upgrading the log management capabilities at my organization.
Elasticsearch, along with Kibana, has provided a wide range of capabilities for our IT teams to investigate issues and create live monitoring environments.
This is being utilized as a central tool for all of our apps organization-wide.
Before Elasticsearch, our teams were finding a hard time investigating issues, tracking the root cause, and resolving them. Elasticsearch have greatly reduced the investigation time for us.

- It's an Open Source tool
- Elasticsearch extends its visualization and analytics capabilities through Kibana, which is a powerful tool
- Elasticsearch provides 3rd party integration facilities using REST API
- Search capabilities can be further improved with a much faster response time on historical logs
- Elasticsearch should have a phone/sms alert feature as well as an event trigger
- Learning guides could be more detailed

An amazing search engine
Elasticsearch is being used for multiple purposes in multiple projects: centralized log management, APM, Metrics Collection as a TSDB, and as a replacement for traditional OLAP databases. It provides a high-performance indexing and search engine, which has become an invaluable tool addressing hard problems that would otherwise be very difficult to solve.
- Ingress and indexing.
- Searching.
- Aggregations.
- Aggregations on top of other aggregations.
- Encryption at rest.
- Has a performance penalty when using inked documents.
Elasticsearch has been a big help for us. We used to work with Application Performance Management Tools that need another layer of visualization and data treatment, and with Elasticsearch we have delivered better insights for our customers.
We use Elasticsearch at our Technology & Services Department to address these issues for our customers:
- Customized Dashboards.
- Anomaly Detection.
- Metrics Predictability.

- Customized Dashboards.
- Anomaly Detection.
- Metrics Predictability.
- Anomaly detection. It can find patterns over a wide variety of metrics and values.
- Behind the walls, Elasticsearch has a robust distributed architecture to support queries and data processing, and it is easy to maintain and scale.
- Elasticsearch has a new Elastic Cloud SaaS solution which is very easy to deploy, set up, and scale with all features and more.
- Elasticsearch has an important security layer to separate access to data and dashboards.
- If you want to explode Elasticsearch's capabilities, you need to have a medium-high SQL and Database knowledge.
- The user interface is heavy in Java requirements, and sometimes you can get some lag displaying heavy results for heavy queries.
- It will be helpful if you can construct Logstash queries with a drag&drop based user interface.

Works well but is difficult to set up and manage
We currently use it to log the details of our RPA processes as they run through their production and development environments. They log back checkpoints, statues and error messages back to the Kibana database we use in conjunction with Elasticsearch.
- Powerful beats modules.
- Later number of input/output pipelines.
- Open documentation.
- Documentation is often incomplete.
- Forums are very full but misleading.
- The programs don't work well together. They have different methodology and flavors in each.
- Different configurations in each element make it difficult to use.

ElasticSearch handles a large number of requests quickly and easily
ElasticSearch is used to store all searchable data indices from our product. We use ElasticSearch because it is extremely fast, highly available, and able to meet the demand of our product. We were using a different index-based search technology before, and it failed terribly. We migrated to ElasticSearch and have been very happy with the results.
- Easy to install
- Easy to use/lots of documentation
- Easy to scale up as demand increases
- The price point for the X-Pack plugins (ie. Security, Alerting, etc.) is a bit high, especially if you only want to do something small and simple and you don't need to leverage the full power of the plugin
- Configuring the right hardware and capacity planning (when at scale) can get really tricky. In order to get the best performance, a lot of tweaking is needed, and not all of the secret tricks are documented
- Getting used to ElasticSearch's query language was a bit of an adjustment. You really have to delve into defining analyzers and tokenizers in order to get application-specific results
Elasticsearch (ES) is being used to measure the performance metrics of our web crawlers for our web metrics department. They employ a series of crawlers: setting up data feeds to an ELK stack to measure and monitor organic messages related to our marketing campaigns. It primarily allows us to bring advanced analytics in-house.
- Free of SQL: ES does not have the overhead of relying on SQL. In fact, you can use most (if not all) DBMs out there.
- Java: Normally, this is not a strength: Java is slow and cumbersome. I believe in this case, it's truly a feature: by utilizing a language with universal support, it makes ES VERY DevOps friendly, simply by being able to focus on Problem-oriented vs Solutions-based thinking.
- Although ES has been known to consume RAM, it's very flexible, and I have implemented on a number of distinct hardware configuration with success.
- Linux: It's not locked down to an OS (which is the way of the future), and as a result-running it on Linux means you get the power of Linux, in a data science package.
- Elastic Search IS a resource hog: most of the time, I will run ES on a dedicated VM (often a dedicated blade, too!) and allow the other components of the stack to run on separate blades/VMs.
- Works great for small projects, but is NOT industrial strength: When you are performing a data architecture project, where you are capturing and mining datasets, ES is fine, until you start getting into much denser data sources (orders to TBs), such that ES will violate Data integrity.
- It only supports JSON output: Which is very friendly to a lot of DevOps/Data Architecture projects but may become a hassle when your endpoints require CVS, XML, etc.

The Best Available
It provides a distributed, multitenant-capable, full-text search engine with an HTTP web interface and schema-free JSON
documents. We use this in our IT department, but also resell it as part of a predictive AIOps platform that offers automation for many of the tedious tasks that data center staff struggle with every day.

- Search
- Correlation
- Analysis
- Big data
- Pagination
- Presentation
- Mapping
We use Elasticsearch for our online (realtime) search engine. We've indexed over 2 billion documents, including every physician, hospital, and clinic in the United States. We started using ES from the beginning since I had a bunch of great experiences with the technology from my last job. We load data into Elasticsearch from multiple locations, including Postgres and BigQuery. On top of Elasticsearch, we've built a number of analytics tools that let us not only search but also deliver analytics for our stored data -- like top physicians performing a specific service and geography-based analyses. Overall we're super happy with Elasticsearch.
- Super-fast search on millions of documents. We've got over 2 billion documents in our index and the retrieve speeds are still in the < 1-second range.
- Analytics on top of your search. If you organize your data appropriately, Elasticsearch can serve as a distributed OLAP system
- Elasticsearch is great for geographic data as well, including searching and filtering with geojson, and a variety of geospatial algorithms.
- Elasticsearch is highly distributed, but it takes time to tune so you get the right performance out of your cluster.
- The query language is not SQL, so it's not a straightforward conversion from an RDBMS to Elasticsearch for searching through data.
- There are lots of ways to insert data into Elasticsearch, and some are better than others (batch vs. single insert). Need to experiment with your own data and environment.
Elasticsearch is being used for multiple purposes at Iconscout. Starting from a search engine to viewing detailed analytics. We're even using it for logging of the server. It helps us to query through the millions of data easily and efficiently.
- Fast Search through millions of data
- Uses a very limited storage to store the data - high compression
- Easy to get started & configure
- Their documentation needs a lot of imporvement
- Difficult to understand query language
- New updates are difficult to adopt

Elasticsearch Review
It is used in our custom software application for advanced searching and filtering capabilities for our users.
- It allows extremely fast search and filtering on large datasets
- It has a very powerful aggregation engine that can allow for tons of customizable analytics and reports.
- The documentation could be a bit more detailed and have more examples, especially for advanced functionality.
- The ability to update/change existing live field mappings would be nice.
- The ingest pipeline structure is a bit more complicated and confusing than previous implementations for using things like attachment plug-ins.

The gold standard for text-based search
We use Elasticsearch to power a web search engine that allows users of our web platform to search for products, content, and more. With Elasticsearch we were able to quickly and effectively develop and deploy a search solution that is fast, scalable, and was a breeze for our developers to implement.
- Lightning fast
- Easily scalable
- Powerful feature set
- Additional complexities when in need of frequent & rapid updates to the Elasticsearch data set
- New syntax can be confusing, particularly with advanced features and more powerful queries

Find more faster with Elasticsearch
We use Elasticsearch to efficiently search large pools of data. Elasticsearch gives us the ability to have blazing fast searches even when doing partial text matches on multiple fields.
- The best solution we've found for blazing fast searches, especially text-based.
- Easy to add nodes for data redundancy.
- Good documentation makes getting up and running easy.
- I found the learning curve fairly difficult having a SQL background.

Enthusiastic for Elasticsearch
We decided to start looking into Elasticsearch after we had good success with using lucene (the full-text search indexer that Elastic uses). We had some queries in Oracle that were running EXTREMELY slow and knew we had to do something for the customer to make their experience better. We had a few thoughts on what we could use and Elasticsearch fit what we really wanted.
- Searching, it does it well and searches are fast...real fast.
- Ease of use, we were able to get an Elasticsearch cluster up and running in a half hour and doing basic searches after that was very easy with simple requests
- Redundancy built in and stability. We haven't had any of our Elastic clusters go down intentionally, but testing out redundancy by removing nodes Elasticsearch has gone flawlessly.
- Only breaking changes between versions when they are absolutely necessary.
- Works well with .Net libraries that are supported and coded by Elastic.
- A bit more of a learning curve for complex searches, indexing more complex things.
- Some of our updates between versions haven't gone as smoothly as we would like, but in more recent versions Elastic has done a much better job at trying to allow for full uptime upgrades.
- Configuration needs to be set up to do larger searches, or more complex searches and at times while starting it wasn't obvious what configuration needed to be changed.

Need fast querying of text data? Go with Elasticsearch!
We use Elasticsearch to store data for quick querying of our various data sets via our APIs. It has allowed us to write APIs that perform much faster compared to their older versions that had complex relational queries.
We also use Elasticsearch to store log data for fast querying via Kibana.
We also use Elasticsearch to store log data for fast querying via Kibana.
- Very fast querying of data, especially text based searches.
- Nice clustering of nodes built in, to ensure a stable, redundant environment.
- Great integration with Kibana for visualizing and exploring data.
- Query syntax can be hard for developers to pick up, especially if they are used to SQL.
- Tooling leaves a lot to be desired, especially compared to the RDMS tooling that is out there.
- Updates to Elastic search data aren't the fastest, especially compared to some other nosql solutions like MongoDB

Elasticsearch for Log Management
We utilize Elasticsearch (with Kibana and Logstash) to provide log management services internally and as an offering to our IT clients. This helps clients meet compliance regulations requiring log review and SIEM implementation without paying the premium at other high-end products. In essence, Elasticsearch allows us and our clients on the platform to gain greater visibility into their applications and endpoints.
- Elasticsearch has a great ecosystem and user base.
- Elasticsearch is easy to use and set up (once you have the basic training).
- The document/searching focused feature of the database is perfect for log management (or any searching) application.
- I wish many of the features in the X-Pack were native.

ElasticSearch is a simple straightforward search engine that literally anyone can get started with!
We use Elasticsearch as the storage/search component of our logging infrastructure (ElasticStack). Once we have broken apart the individual variable components of each log as their own variable type using Logstash, we store those records in to Elasticsearch. Kibana queries Elasticsearch to display the resulting data. We also utilize Elasticsearch to display the cluster status for each of our markets across our entire web cluster using an internal reporting tool we wrote.
- Effortless to set up. Literally set the memory thresholds for Java and start throwing JSON formatted records in to the database, it "Just Works". Even clustering is automated as the cluster finds other ElasticSearch servers on the network and assigns each a name.
- Very simple to use interface either through it's RESTFUL API (ala Curl) or via its speedy protocol on port 9300. Once records are added, the very easy to use Apache Lucene syntax is supported to extract data.
- It's search capabilities are fast on huge datasets, even on very modest hardware. Our organization operates in the hundreds of servers taking thousands of requests a second, each with it's own log w/ a 2 week retention. The ElasticSearch server we recently decommissioned was Pentium 4 Netburst class Xeon, it rarely skipped a beat.
- Setting Java memory thresholds can be a pain for those not accustomed to things like Eden Space & Old Generation which can lead to over allocation, or more likely, under allocation. Apache Solr had a similar issue. It would be nice if the program would take an extra step and dogfood it's own advice by analyzing the system & processes to return a solid recommendation for that configuration. The proper configuration information is outlined in the documentation, it would be nice if that was automated.
- The only health check that ElasticSearch reports back is a "red" status without any real solid information about what is going on, though its usually memory thresholds or disk I/O. I am currently on ElasticSearch 1.5 so that may have changed for newer versions. When the status goes "red", I as the administrator of the software, feel like I lose control of whats going on which should rarely happen. Something more verbose would eliminate that.
- This is more of a critique of the ElasticStack in general. The whole top to bottom stack is starting to get feature creep with things that are better suited in other software and increasing the barrier for entry for people to get started with setting up a robust logging infrastructure. ElasticSearch as a storage search engine, is pretty streamlined, but I can see that the tools that comprise the ELK Stack are going to require a certification with constant study at some point. During major release for Logstash a while back, it literally took a month to learn a new language because Elastic completely changed the syntax. For a medium sized organization of only a couple of admins, that is a pretty high bar where time is money. They really should work on refining/automating the tools & search engine they have, instead of shoehorning/changing things on to an already rock solid foundation.

Excelent choice for data analytics and search engine
Elasticsearch helped us to provide comprehensive reports, and frequent queries on our data (millions of rows), provided us a performance that we could not achieve before (though we have only 40 concurrent users at most) We also consolidate data from many sources within our company, and elasticsearch made it easy for us to do data analyzing, to have many useful insights of our data; things that we could never do (so easily) in the past.
- Comprehensive reports and queries
- Data analytics
- A better way to provide custom functions. I struggled with implementing the PercentileExc (exlusive) funtion, the one that Excel provided, because the business users requested it.
- Better IntelliSense in development console, when the query is complex, I often lost the IntelliSense feature. The “exists” query is not supported by IntelliSense.

Elasticsearch review
Elasticsearch is used across the whole org. It's used mainly for storing and searching application logs. We have many elastic clusters set up differently. Sometimes it's one cluster per app; sometimes it's one cluster for many apps; depending upon the volume of data being generated. Elasticsearch is used mainly for debugging purposes rather than metrics, but sometimess it's used along with Kibana to visualize metrics also.
- Elasticsearch search with its clustering solution provides a scalable logging solution. A number of query nodes, data node and master node can be added on demand to make the whole system very scalable making it possible to store and search terabytes of data.
- Elasticsearch provides logstash, file beat, and many others. It makes it really easy to ingest a log with less setup.
- Elasticsearch query language is based on Lucene and is very powerful.
- Elasticsearch is mostly free except a few features such as authentication and authorization; making it really financially economical for companies to deploy it on large scale.
- Elasticsearch doesn't have a free alerting solution. It has elastalert but it's not comparable to the paid version.
- It's lacking authentication and authorization which makes Graylog a more enticing option.
- It's lacking a mechanism to protect cluster against runoff queries. Can bring down cluster to its knees.

Developer's Elasticsearch Review
Elasticsearch is currently in our organization for multiple use cases. With the data volume growing huge and rapidly, we push the data into an Elasticsearch cluster setup. We collect logs from multiple systems and push into E C using logstash and few other message brokers system. We collect telemetry from multiple systems and run algorithms to analyze the data.
- Indexing
- Text analysis
- Time series data handling
- Connector to other big data software
- Plugins to visualize the data other than Kibana
- Better query editor

Find things with Elasticsearch
The first use case is log aggregation. We have a number of micro-services running, some of them in Docker, and we use the ELK to ensure we have easy access to our most recent logs. This proves invaluable for fault detection and diagnosis and is used primarily by engineers. Another use case in a customer-centric search index. Each of our customers is described by a set of data points that come from various sources and are indexed in Elasticsearch. The index is later used by marketing, customer service, and other departments to get quick insights on our customer base.
- Flexible and advanced search.
- Ease of creating time-based indices and automatic archiving of old indices.
- Quick data ingestion.
- Configuration. Looking forward to seeing Elasticsearch detecting hardware specs and self-adjusting its config.
- The lack of _changes streams. They were promised to appear in 2.0...
- The price of the hosted solution could be lower.
