Package: Zend_Search_Lucene\Analysis

An Analyzer is used to analyze text.

It thus represents a policy for extracting index terms from text. Note: Lucene Java implementation is oriented to streams. It provides effective work with a huge documents (more then 20Mb). But engine itself is not oriented such documents. Thus Zend_Search_Lucene analysis API works with data strings and sets (arrays).
