Examples of org.apache.lucene.index.Term

org.apache.lucene.index.Term
A Term represents a word from text. This is the unit of search. It is composed of two elements, the text of the word, as a string, and the name of the field that the text occurred in. Note that terms may represent more than words from text fields, but also things like dates, email addresses, urls, etc.
