OpenSearch – an open source enterprise search server based on a fork of Elasticsearch 7.MongoDB Atlas Search – a cloud-native enterprise search application based on MongoDB and Apache Lucene.It is also used by the Human Metabolome Database (HMDB) and the Toxin and Toxin-Target Database (T3DB). The Socialtext wiki software uses this search engine, and so does the MojoMojo wiki. Kinosearch – a search engine written in Perl and C and a loose port of Lucene.Elasticsearch – an enterprise search server released in 2010.DocFetcher – a multiplatform desktop search application.

CrateDB – open source, distributed SQL database built on Lucene.Apache Solr – an enterprise search server.Apache Nutch – provides web crawling and HTML parsing.However, several projects extend Lucene's capability: Lucene itself is just an indexing and search library and does not contain crawling and HTML parsing functionality. In contrast, citation-based document similarity measures tended to be more suitable for recommending more broadly related documents, meaning citation-based approaches may be more suitable for generating serendipitous recommendations, as long as documents to be recommended contain in-text citations.

In a comparison of the term vector-based similarity approach of 'MoreLikeThis' with citation-based document similarity measures, such as co-citation and co-citation proximity analysis, Lucene's approach excelled at recommending documents with very similar structural characteristics and more narrow relatedness. For example, Lucene's 'MoreLikeThis' Class can generate recommendations for similar documents. Lucene has also been used to implement recommendation systems. Lucene includes a feature to perform a fuzzy search based on edit distance.
APACHE LUCENE RELEASE HISTORY FULL
While suitable for any application that requires full text indexing and searching capability, Lucene is recognized for its utility in the implementation of Internet search engines and local, single-site searching.
