    Solr spins up nicely and works effectively for small enterprise environments providing helpful mechanisms for fuzzy searches and facetted searching. For larger enterprises with complex business solutions you'll find the need to hire an expert Solr engineer to optimize the powerful platform to your needs. Internationalization is tricky with Solr and many hosting solutions may limit you to a latin character set.

    I think Guru is well-suited to organizations with subject matter experts committed to maintaining documentation. Guru cannot be managed by a single admin. It's essential that the SMEs are on board and are expected to participate in Guru as part of their role responsibilities. I'm not sure how well Guru would work for larger organizations with more information to house. I've only ever used Guru in SMBs with about 250 employees. It works well for that size.

    Pros
    Apache
    • Easy to get started with Apache Solr. Whether it is tackling a setup issue or trying to learn some of the more advanced features, there are plenty of resources to help you out and get you going.
    • Performance. Apache Solr allows for a lot of custom tuning (if needed) and provides great out of the box performance for searching on large data sets.
    • Maintenance. After setting up Solr in a production environment there are plenty of tools provided to help you maintain and update your application. Apache Solr comes with great fault tolerance built in and has proven to be very reliable.

    • Easy to learn. Anyone can make cards and use the AI to make them professional.
    • Answer questions about my business, essentially a wiki for everything we do.
    • The research mode is amazing. Full reports on various types of information including some rather complex topics. Complete with citations of where the information came from.
    • Admins can manage a hierarchy to keep information secure and available to the correct people.

    Cons
    Apache
    • These examples are due to the way we use Apache Solr. I think we have had the same problems with other NoSQL databases (but perhaps not the same solution). High data volumes of data and a lot of users were the causes.
    • We have lot of classifications and lot of data for each classification. This gave us several problems:
    • First: We couldn't keep all our data in Solr. Then we have all data in our MySQL DB and searching data in Solr. So we need to be sure to update and match the 2 databases in the same time.
    • Second: We needed several load balanced Solr databases.
    • Third: We needed to update all the databases and keep old data status.
    • If I don't speak about problems due to our lack of experience, the main Solr problem came from frequency of updates vs validation of several database. We encountered several locks due to this (our ops team didn't want to use real clustering, so all DB weren't updated). Problem messages were not always clear and we several days to understand the problems.

    • Lack of in-app advanced/granular usage and validation analytics.
    • Unreliability of Google Chrome extension.
    • Left navigation is not intuitive nor descriptive--I hunt and peck.
    • The search field is limited to keywords, so I sometimes have to "trick" it by including extra words in the title of a card.

    I rated Guru a 9 out of 10 for renewal likelihood because it has significantly enhanced our processes and customer satisfaction in the automotive rental company. Guru’s user-friendly interface and organized knowledge base make it easy to access and update essential information, which is crucial for maintaining high operational standards. The tool’s integration with other platforms, like the Guru Chrome extension, streamlines our workflow, increasing efficiency and productivity. One of the standout features is the ability to favorite cards, allowing quick access to frequently used information, which saves time and ensures accuracy in customer interactions. Additionally, Guru’s analytics feature helps us identify which resources need updating, ensuring our knowledge base remains relevant and effective. The only reason it’s not a perfect 10 is occasional slow performance and occasional inaccuracies in search results. However, these minor issues do not overshadow the overall benefits Guru provides. Its consistent updates and reminders further enhance our ability to deliver excellent customer support, making it an indispensable tool for our team.

    Usability

    It takes some time to deploy and currectly maintein it. And also, to learn how to use and integrate in the enviroment as well. Once you get theses steps done, it usability is very simple, and almost of the time it don't require no further attention on it. Even for maintence, if you deploy it on a cluster mode, it is very reliable and easy to take one host down.

    While using the GURU card, the level of response I get is quality. The rate at which my responses and prompts through the search or chat is fast, responsive, and high-quality. I can easily see when the cards were modified, who modified them, and the new information available on the GURU.

    Highly reliable day‑to‑dayGuru is consistently available when I need it. The platform loads quickly, search works reliably, and I rarely experience downtime or slow performance. It’s dependable enough that teams can trust it as a daily source of truth. Minimal unplanned outages or errors. In my experience, unplanned outages or errors are extremely rare. Even during high‑usage periods or heavy workflows, Guru remains stable and responsive.

    Pages load quickly and consistently. Guru’s interface is lightweight, so cards, boards, and search results load fast with very little lag. Even when navigating between collections or opening larger cards, performance stays smooth and reliable. Integrations perform well without slowing systems down. Using Guru through the browser extension or Slack integration doesn’t noticeably impact performance. Cards surface quickly, and interacting with the integrations feels just as smooth as using Guru directly.

    The support has been wonderful - probably one of the best things about Guru. We have a Slack channel where we can reach out and interact with our Guru CSM, and she is extremely responsive. Even if the solution isn't always easy, she provides all the necessary steps and options clearly.

    The online, on-demand training available was very good. I do wish we had done live online training as an org so that everyone had the same opportunity to learn the value and best practices. I completed the online, on-demand trainings personally, then turned around and taught the org, but I wish I had let the Guru experts do the heavy lifting for me!

    You will need a very strong team of guru champions in order to get EVERYONE and EVERYTHING on Guru, it takes some craziness and over talking about guru everywhere to get people to be exicted, contribute and use. If you are starting any kind of buisness and you need KB, just go for guru as fast as you can because when you will grow you will thank yourself.

    We tried to use both Elasticsearch and Swiftype with Drupal 8 but there are currently no good modules that integrate Drupal with those solutions. So Solr was really the only option for a Drupal 8 web site. It's not as easy to learn or use as Swiftype, but in the end I think it will be a little less expensive and offer more customization and flexibility.

    Compared with the vendors that we initially evaluate the AI functionality of, Guru makes the difference and also the interface capabilities, making it user-friendly, being able to build it up in a professionally way. there are no limitations on the customization of the interface, which supports multiple use cases at once and can apply to different teams that have different needs

    Guru is somewhat expensive compared to what our org is typically willing to spend on software solutions. Additionally, there is a price difference per seat when paid monthly versus annually, which was a big downside for us as my company didn't want to commit to an annual cost.

As teams grow, it’s simple to create new Collections, Boards, and permission sets without disrupting existing structures.

    • It has enabled my organization to find information faster by being a one-stop service to search across content that were indexed from varying sources.
    • By using synonyms and usual lemmatizations / stemming, it enabled discovery of new content following every search.

    • Guru allows our team to quickly reference available learning/knowledge materials with our clients on a daily basis and provide better support at every outreach
    • With that said, spreading those same resources across two major global teams in the USA and Germany can lead to some inconsistencies. The i-frame process is not very intuitive for this scenario and our team treats policy/procedural differences as separate card or article entities.
    • Guru allowed our organization to pioneer and establish a dedicated knowledge team component, of subject matter experts who work in tangent with existing resources, create new ones, and vet collective knowledge.
