That being said, its limitations hover over the fact that there are no formal support contracts, no assured availability of training or formalized release of testing programs. It also lets users produce and distribute derivates and proprietary work without any degree of restrictions, making it one of the most efficient, scalable and accurate technology.

The fact that Lucene is an Apache open source software leverages a host of benefits to its end-users in terms of free use, independence and control one usually gets by writing software himself.

What’s more, its indexes are portable across platforms too. Probability – Lucene runs on just about any platform that is compatible with Java. Holistic results – Lucene performs a full-result processing that includes relevancy-sorting, sorting using date or any given field and also dynamic summaries. Speed – Lucene that works entirely on Java performs at a sub-second for most queries to deliver results, enhancing organizational efficiency.Ĭomplete query capability – The search technology encompasses everything from spell-checking proximity operators to enabling multi-lingual search. It’s configurable storage engine, pluggable ranking model and flexible faceting further enhances the efficiency of the algorithm mechanism.Ĭross-platform solution – As an open source software below the Apache, Lucene lets one use its license for both, commercial and open source programs. The results would be sorted by using any field as their parameters. Powerful and precise algorithm – The search technology of Lucene derives the best results on priority. Its incremental indexing works as fast as batch indexing. Scalable Indexing – Lucene performs at 150 GB/hour on modern hardware with a minimal RAM requirement of about 1MB heap. Organizations the world like AOL, IBM, Comcast Interactive Media amongst many others bank on this technology for its high performance, relevancy and scalability.Īs a 3rd generation search technology, Lucene power-packs an array of features such as text-compression and partitioned index strategy to enhance both, query performance and index flexibility, to name a few.

Written in Java, Lucene is compatible with near about any application that requires full text search, especially when it comes to cross-platform.

your server is well below its red-line QPS throughput capacity), Lucene will use multiple concurrent threads to find the top overall hits for each query.”Īpache Lucene 8.4.1 can be downloaded here.Apache Lucene is a high performance search technology which is available for free as open source from the Apache Software Foundation. “If you pass an Executor and your CPUs are idle enough (i.e. The main features of the Apache Lucene project are indexing, full-text search, clustering in dynamic mode, search in faceted mode, document handling, NoSQL features, etc. It is based on the Apache Lucene project. PMC member and committer for the Apache Lucene project Michael McCandless explains this in detail in a blog that states: “Lucene’s IndexSearcher class, responsible for executing incoming queries to find their top matching hits from your index, accepts an optional Executor (e.g. Apache Solr is an enterprise search platform that is purely written in Java programming language. The engine itself is incredibly robust, and while the engine is commonly used in a one thread per query manner when initiating a search, the engine can actually execute a single query concurrently using multiple threads. Known as an inverted index it works in a similar manner as the index of a book. It does so because instead of searching text or content directly, it instead searches an index which has been created in relation to that content. One of the main reason that Apache Lucene is considered in such high regard is that it can return search responses quickly.
