public final class SynonymFilter
- extends TokenFilter
SynonymFilter handles multi-token synonyms with variable position increment offsets.
The matched tokens from the input stream may be optionally passed through (includeOrig=true)
or discarded. If the original tokens are included, the position increments may be modified
to retain absolute positions after merging with the synonym tokenstream.
Generated synonyms will start at the same position as the first matched source token.
