7. Apache Lucene for full text Search In Lucene, a Document is the unit of search and index. An index consists of one or more Documents, Indexing involves adding Documents to an IndexWriter, and searching involves retrieving Documents from an index via an IndexSearcher. A Document consists of one or more Fields. A Field is simply a name-value pair. For example, a Field commonly found in applications is title. In the case of a title Field, the field name is title and the value is the title of that content item. Indexing in Lucene thus involves creating Documents comprising of one or more Fields, and adding these Documents to an IndexWriter http://www.lucenetutorial.com/basic-concepts.html Technologies for Websites
