Reviews
(1-18 of 18)- Indexing text data
- Aggregations allow users to progressively add search criteria to refine their searches
- Find trends in our data with Aggregations
- Integrate text Search our taxonomy Search
- Joining data requires duplicate de-normalized documents that make parent child relationships. It is hard and requires a lot of synchronizations
- Tracking errors in the data in the logs can be hard, and sometimes recurring errors blow up the error logs
- Schema changes require complete reindexing of an index
Elasticsearch Review
- 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.
Very useful for eCommerce
- 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.
An amazing search engine
- Ingress and indexing.
- Searching.
- Aggregations.
- Aggregations on top of other aggregations.
- Encryption at rest.
- Has a performance penalty when using inked documents.
We use Elasticsearch at our Technology & Services Department to address these issues for our customers:
- 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.
Elasticsearch has potent visualization features with Canvas and OOB Dashboards that can respond to business and technical requirements.

Find more faster with Elasticsearch
- 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.
Elasticsearch for Log Management
- 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.
Excelent choice for data analytics and search engine
- 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 is a simple straightforward search engine that literally anyone can get started with!
- 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.
As a developer looking for a quick and simple search engine which has little configuration required, ElasticSearch is fast and perfect for that solution. Literally throw JSON records in to the database and push a request to get JSON out, exceptionally straightforward.
One of the best search engines out there
- Search
- Organize data
- Scale
- Mapping and data type auto conversion
Elasticsearch is the way to go!
- Fuzzy query matching
- Indexing and Sharding data
- High availability and cluster managment
- A better user interface
- Better integration with AWS
Stretch Your Ambitions With ElasticSearch
- Store large numbers of documents in a redundant, distributed fashion across multiple hosts. It handles sharding out of the box with a minimal amount of configuration.
- Extensive search capabilities, particularly full text search. It also supports aggregations/facets and geospatial searching.
- Native REST API is great for web applicaitons.
- The online documentation is very difficult to use, both as a teaching tool and as a quick reference. The search syntax is arcane and not particularly "human friendly" and examples from the documentation are often insufficiently detailed to apply directly.
- ElasticSearch is touted as "schemaless" when in fact mappings (aka schemas) are required for all but the most basic use cases.
Elasticsearch - go for it!
- The snippet that we get back before and after the search words is very helpful for the scientists to get the right content.
- At my previous job with a simple 3 node cluster, Elasticsearch did not do a good job in electing a new master, when the master node went down. Many times, I had to stop and restart all the nodes to make it function again. I have heard implementation models where customers had dedicated multiple nodes just for master.
- It indexes anything. Just use structured logging to begin sending messages to it.
- Kibana, the UI for it, allows you to easily build dashboards with real-time widgets.
- The REST API for Elasticsearch is well-written, should you choose to incorporate the data on your own custom application.
How Elasticsearch changed our culture
- Consolidate data
- Searchable
- Graphable
- Kibana GUI could use some work, better than Logstash though
- URL shortening was just released
- Graph coloring was just released
