Apache Lucene Software Library

An Apache Lucene Software Library is an Apache Java-based document search software library.

• Context:
  • It is managed by the Apache Lucene Project.
  • It can a store Text Item as a Lucene Document.
  • It can create and manage a Lucene Index (an inverted index).
  • It can support a Lucene Query, such as a Phrase Query, a Wildcard Query, a Proximity Querys, or a Range Querys.
  • It can use a Vector Space Model implementation of search.
  • It can be used to create an Apache Lucene-based Platform (to develop an Apache Lucene-based system).
  • …
• Example(s):
  • Apache Lucene v6.4.0 (2017-01-17)[1].
  • Apache Lucene v3.4.0 (2011-09-09)[2].
  • Apache Lucene v2.9.4 (2013-01-15)[3].
  • …
• Counter-Example(s):
  • other Apache Framework's such as: Apache Solr, Apache UIMA, Apache Hadoop, Apache OpenNLP, or Apache Nutch.
  • a GATE Framework.
  • a Xapian Software. http://en.wikipedia.org/wiki/Xapian
  • a Sphinx Softwarre. http://en.wikipedia.org/wiki/Sphinx_%28search_engine%29

    • incremental indexing as fast as batch indexing
    • index size roughly 20-30% the size of text indexed
  • Powerful, Accurate and Efficient Search Algorithms
    • ranked searching -- best results returned first
    • many powerful query types: phrase queries, wildcard queries, proximity queries, range queries and more
    • fielded searching (e.g., title, author, contents)
