All Implemented Interfaces:

Closeable, AutoCloseable

public class TibAffixedFilter
extends org.apache.lucene.analysis.TokenFilter

Removes འི, འོ, འིའོ, འམ, འང and འིས characters at end of token.

The འི is an affixed particle that can be usefully ignored in search and indexing so that "པོ" and "པོའི" will match. This should help searches to be more lenient.
