\Zend_Search_Lucene_Analysis_Analyzer
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).
