Analyzers for indexing content in different languages and domains.
For an introduction to Lucene's analysis API, see the org.apache.lucene.analysis package documentation.
This module contains concrete components (CharFilters,
Tokenizers, and (TokenFilters) for
analyzing different types of content. It also provides a number of Analyzers
for different languages that you can use to get started quickly. To define fully custom Analyzers
(like in the index schema of Apache Solr), this module provides CustomAnalyzer.
