Besides that, the Apache Solr is also written in java. It is very easy to use and very easy to understand. The main features provided by the Apache Solr, for example, full-text search, real-time indexing, dynamic clustering, database integration, rich document handling and, NoSQL features. **What do you dislike about Apache Solr?** The Apache Solr is an average tool use for document indexing, which can be used for searching and data retrieval.

Currently it has to be wrapped by another service that does authentication. **Recommendations to others considering Apache Solr:** It is used whenever high and large data volume needs to be filtered and classified for search and filtering.Hence this is very poweful tool to be used . Alternative tools like elastic search can also be used and utilised in multiple search engine across the organisation whenever there is need to search on large volume of data. Hence it becomes essential to deploy , handy , quick and light weight tool . I would recommend this tool for all the organisation which is looking for easy search engine on high volume of data. This is big deal when performance is critical for frontend application across any organisation **What problems is Apache Solr solving and how is that benefiting you?** it is powerful search engine to serve large data of information which is best used when quick search results are requested by the frontend system ### 11.

If you are launching a search product and expect demand to grow this is an excellent option. The support community is also excellent. One of the best Open Source projects out there. **What do you dislike about Apache Solr?** For some tasks working with Solr requries customization beyond what is needed with commercial products. Solr lacks some data filters that commercial rpoducts offer. Entity extraction is basic. **Recommendations to others considering Apache Solr:** Look at all the features that your project requires so that you can identify functionality that is off the shelf vs custom. **What problems is Apache Solr solving and how is that benefiting you?** Online publishing. Performance and flexiblity and extensibility are all excellent. ### 13. Solr is a great product for giving users an easy way to find data **Rating:** 5.0/5.0 stars **Reviewed by:** KC B. | Vice President of Product and Technology, Mid-Market (51-1000 emp.) **Reviewed Date:** January 11, 2018 **What do you like best about Apache Solr?** Solr strength is the fact that it can quickly search through billions (yes with a B) or records to ptu the right data in front of a user. **What do you dislike about Apache Solr?** There is not much to dislike about solr. sometimes solr cloud acts up and does not fail over correctly. **Recommendations to others considering Apache Solr:** if you need to search massive amounts of data, Solr is the best. **What problems is Apache Solr solving and how is that benefiting you?** Search through millions or records with multiple facets within each record to get the right record in from of the searcher fast. ### 14. Powerful, flexible search engine **Rating:** 3.5/5.0 stars **Reviewed by:** Marshall M. | Software Engineer, Enterprise (> 1000 emp.) **Reviewed Date:** September 08, 2016 **What do you like best about Apache Solr?** Solr is a very powerful, very flexible search engine. It is very fast and stable when configured correctly. Solr allows you to build your own custom request handlers and allows you to import data from pretty much any datasource. It is extendible, allowing you write your own plugins/importers to expand the built-in functionality. It's performance, scalability, and extendability make it a solid choice for powering real-time searches. **What do you dislike about Apache Solr?** At least with version 4.3-4.10, the documentation for Solr was very lacking, and it is difficult to find help with things. There are a lot of features, particularly in your configurations, that can take a bit to understand and get setup correctly. There has been a lot of guesswork in figuring out some of these features, and it seems like there is a lot that could be better documented to help identify where certain things can be used. Dealing with Zookeeper can also be a hassle. Updating the configs through Zookeeper has not been the most straightforward thing. **Recommendations to others considering Apache Solr:** If you do not have a search service and are relying on direct database reads for your searches, I'd highly recommend looking into using Solr for your search platform. Solr provides a lot of different ways to parse your search input and ways of improving your consumers' search experience. Newer versions of Solr (5, 6) are greatly improved and easier to get going with, along with better documentation, and are highly recommended. **What problems is Apache Solr solving and how is that benefiting you?** Solr provides nearly all of the search logic for our products. Our dataset is fairly large, and Solr handles this very effectively. There have been some unique challenges in setting it up to take advantage of all that Solr has to offer, but it provides a very good search engine that works for us and our users. ### 15. Using to search media database **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Photography | Small-Business (50 or fewer emp.) **Reviewed Date:** April 11, 2017 **What do you like best about Apache Solr?** Speed, very fast and easy to use and has configurations when you want to dive deeper **What do you dislike about Apache Solr?** Indexing and text based admin system, but mostly writing this because I have to find dislikes. **Recommendations to others considering Apache Solr:** Try it out. **What problems is Apache Solr solving and how is that benefiting you?** Speed of search results. ### 16. Used as a replacement for Oracle Search with great improvements **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Online Media | Mid-Market (51-1000 emp.) **Reviewed Date:** March 22, 2016 **What do you like best about Apache Solr?** Solr is a very quick and easy way to search for keywords within a document, the ability to add weightings to search terms to increase the outcome of search relevance gives it great flexibility. It has a great user interface to be able to search your data and create your search query, as well as check the status of the server and cache. It was easy to hook this search into our code base, using the search url **What do you dislike about Apache Solr?** The way you index the data to Solr could be improved, it has a document feeder built in but isn't the easiest to use and is recommended to not be used in a production environment, although we have done this in the past. Which means a separate application needs to be written to insert your data. Creating a SOLR cloud isn't as straight forward as it could be, as it needs to use Zookeeper, which means an additional server/service to maintain, other similar search products do not require this. **Recommendations to others considering Apache Solr:** Making the switch was relatively easy task and the increase on performance was well worth it. **What problems is Apache Solr solving and how is that benefiting you?** We needed to improve the relevance and performance of our existing search, and by using SOLR did both of these with the added benefit of reducing the load on our Oracle Database. We improved our relevance and customers immediately noticed the difference. That was with the 'out-of'the'box' settings, we can see how this can be improved further. ### 17. Best Search Engine so far **Rating:** 5.0/5.0 stars **Reviewed by:** Ashish M. | Full Stack Engineer, Computer Software, Mid-Market (51-1000 emp.) **Reviewed Date:** March 18, 2016 **What do you like best about Apache Solr?** The customisability of the solr is so good that anyone can set it up and customise it for his/her needs Aslo the documentation provided is too good The inbuilt filters are more than sufficient for any of your needs and also you can customise them as per your need there are various features of solr that are helping us in our buisnesss **What do you dislike about Apache Solr?** I have had many issues with multi word synonyms it simply doesn't work **Recommendations to others considering Apache Solr:** If you have huge database with huge raw text docs you can go for solr else database search is ok to use **What problems is Apache Solr solving and how is that benefiting you?** We are solving problems for tax professionals to find rulings . Usually to find any previous ruling user has to go through 12 huge books with 10's of thousands of pages each so that was very time consuming task but now through our system people and find their resources in no time ### 18. For your search engines! **Rating:** 4.0/5.0 stars **Reviewed by:** Cataldo M. | Assistant Professor (Ricercatore a Tempo Determinato), Research, Enterprise (> 1000 emp.) **Reviewed Date:** October 19, 2016 **What do you like best about Apache Solr?** Good user interface, very nice experience.

It allows us to write queries on the dataset to inspect our data in various ways that is often hard to do in Cassandra alone. This has saved us time and thusly money. ### 20. Solr search **Rating:** 4.0/5.0 stars **Reviewed by:** Timothy S. | Principal Developer Advocate, Small-Business (50 or fewer emp.) **Reviewed Date:** January 20, 2016 **What do you like best about Apache Solr?** It works, it's fast and very stable. It's on top of Lucene which is pretty much the only open source solid search software available. SOLR is tied in with some hadoop distributions. It works and once you understand SOLR and LUCENE you are good. **What do you dislike about Apache Solr?** Between Solr and ElasticSearch, there is a constant struggle to pick the best one. ElasticSearch is part of ELK and ties in well with LogStash and Kibana which makes it great for logs and big data stuff. **Recommendations to others considering Apache Solr:** Try elastic search and solr. Add some logs and see which works best for your particular access methods and queries. They are very similar but elasticsearch is better for REST access. **What problems is Apache Solr solving and how is that benefiting you?** Searching log files for data. We were able to do so without buying an expensive license from Splunk. ### 21.

A Simple, Yet Capable Search Platform **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Restaurants | Enterprise (> 1000 emp.) **Reviewed Date:** January 30, 2016 **What do you like best about Apache Solr?** Solr is a fairly straight forward product, that does what ti's supposed to with minimal maintenance. The platform is easily administrated via web portal, and allows for thorough awareness and assessment of the platform itself at any time. **What do you dislike about Apache Solr?** We are on an older version of Solr, so most of my dislikes around the clunkiness of the UI has been fixed in newer versions as far as I can tell.

Real time complex search with SOLR **Rating:** 4.5/5.0 stars **Reviewed by:** Wayne L. | Database Architect, Hospital & Health Care, Mid-Market (51-1000 emp.) **Reviewed Date:** April 11, 2015 **What do you like best about Apache Solr?** * Powerful real time search capability. SOLR can do partial matching search, phonetic search, synonym search and return the result instantly. * Distributed architecture for scalability and availability. * Open source with low cost of ownership **What do you dislike about Apache Solr?** * CPU consumption can be high in some cases. * No built-in monitoring and alerting function for production system. **Recommendations to others considering Apache Solr:** If you need real time search of word or partial word, word synonyms, SOLR is for you. It is relatively easy to setup once you passed the not so great documentation and it is cost effective. The performance is good and very scalable. **What problems is Apache Solr solving and how is that benefiting you?** We use SOLR for two difficult business challenges: * Type ahead search. The application needs to build a short list of match words based on users input as they typing into a search field. The search field is unified search field, that means multiple data types to be searched. For example, the field can be built for search a person. As an user typing, front end client sends the partial input to SOLR to search person's first name, last name, phonetic and spelling variation of the names, social security number, bank account number, application IDs and so on. If an user typing first two letters of name "Mike" The search needs to return a list of matching words before user typing the third letter "k". The match word can be Mike, Micheal, McMillan or a system ID of MI12345. * Record reconciliation. The application has data feeds from various data source and data needs to be annotated and cross reference to each other. One example is using SOLR to build a ranking system to identify the like-hood of two persons from two data sources are the same person in real world, based on social security number, name, gender, birthday, address, credit card number and so on. The data source may contain one or more above attributes for person identification. SOLR enable us to build customizable search function quickly that perform and scale well. We had extensive research on other technologies, such as database text indexing and google search but found SOLR is the best match for our needs. ### 26.
