Solr fits better into enterprise applications that already implement big data ecosystem tools, such as Hadoop and Spark. Elasticsearch is focused more on scaling, data analytics, and processing time series data to obtain meaningful insights and patterns. Its large-scale log analytics performance makes it quite popular.
Solr (pronounced “solar”) is an open-source enterprise-search platform, written in Java, from the Apache Lucene project. … It uses the Lucene Java search library at its core for full-text indexing and search, and has REST-like HTTP/XML and JSON APIs that make it usable from most popular programming languages.
Moreover, What is SOLR used for?
Solr is a popular search platform for Web sites because it can index and search multiple sites and return recommendations for related content based on the search query’s taxonomy.

How does SOLR search engine work?
Solr works by gathering, storing and indexing documents from different sources and making them searchable in near real-time. It follows a 3-step process that involves indexing, querying, and finally, ranking the results – all in near real-time, even though it can work with huge volumes of data.
Why SOLR is fast?
A Lucene (the underlying library used by Solr) index is made of a read-only segments. This allows Lucene to run range queries very efficiently. Since your use-case seems to leverage numeric range queries a lot, this may explain why Solr is so much faster.
How does SOLR search work?
Solr is able to achieve fast search responses because, instead of searching the text directly, it searches an index instead. This is like retrieving pages in a book related to a keyword by scanning the index at the back of a book, as opposed to searching every word of every page of the book.
Is SOLR free?
Apache Solr (Searching On Lucene w/ Replication) is a free, open-source search engine based on the Apache Lucene library. Solr, however, is more than a search engine — it’s also often used as a document-based NoSQL database with transactional support that can be used for storage purposes and even a key-value store.
Can SOLR be used as a database?
Yes, you can use SOLR as a database but there are some really serious caveats : Furthermore, SOLR does NOT stream data — so you can’t lazily iterate through millions of records at a time. This means you have to be very thoughtful when you design large scale data access patterns with SOLR.
What database does SOLR use?
Here’s how to get started. Apache Solr is a subproject of Apache Lucene, which is the indexing technology behind most recently created search and index technology. Solr is a search engine at heart, but it is much more than that. It is a NoSQL database with transactional support.
Which is better Elasticsearch or SOLR?
Solr fits better into enterprise applications that already implement big data ecosystem tools, such as Hadoop and Spark. Elasticsearch is focused more on scaling, data analytics, and processing time series data to obtain meaningful insights and patterns. Its large-scale log analytics performance makes it quite popular.
What is Elasticsearch good for?
Elasticsearch is used for a lot of different use cases: “classical” full text search, analytics store, auto completer, spell checker, alerting engine, and as a general purpose document store.

Does SOLR need a database?
Almost always, the answer is yes. It needn’t be a database necessarily, but you should retain the original data somewhere outside of Solr in the event you alter how you index the data in Solr. Unlike most databases, which Solr is not, Solr can’t simple re-index itself. Unloading all the content from Solr can be slow.
What is SOLR database?
