- All Implemented Interfaces:
- Closeable
public class SimpleAnalyzer
- extends org.apache.lucene.analysis.Analyzer
This analyzer is used when "other" is chosen as the indexing language.
It is used instead of the Lucene SimpleAnalyzer because it indexes numbers as well as letters, and includes the SubtokenFilter.
