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年01月17日)[1].
  • Apache Lucene v3.4.0 (2011年09月09日)[2].
  • Apache Lucene v2.9.4 (2013年01月15日)[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

  • Scalable, High-Performance Indexing
    • over 20MB/minute on Pentium M 1.5GHz
    • small RAM requirements -- only 1MB heap
    • 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)
    • date-range searching
    • sorting by any field
    • multiple-index searching with merged results
    • allows simultaneous update and searching
  • Cross-Platform Solution
    • Available as Open Source software under the Apache License which lets you use Lucene in both commercial and Open Source programs
    • 100%-pure Java
    • Implementations in other programming languages available that are index-compatible
