Class PhoneticFilterFactory
java.lang.Object
org.apache.lucene.analysis.AbstractAnalysisFactory
org.apache.lucene.analysis.TokenFilterFactory
org.apache.lucene.analysis.phonetic.PhoneticFilterFactory
- All Implemented Interfaces:
ResourceLoaderAware
Factory for
PhoneticFilter
.
Create tokens based on phonetic encoders from Apache Commons Codec.
This takes one required argument, "encoder", and the rest are optional:
- encoder
- required, one of "DoubleMetaphone", "Metaphone", "Soundex", "RefinedSoundex", "Caverphone" (v2.0), "ColognePhonetic" or "Nysiis" (case insensitive). If encoder isn't one of these, it'll be resolved as a class name either by itself if it already contains a '.' or otherwise as in the same package as these others.
- inject
- (default=true) add tokens to the stream with the offset=0
- maxCodeLength
- The maximum length of the phonetic codes, as defined by the encoder. If an encoder doesn't support this then specifying this is an error.

- 3.1
- See Also:
- SPI Name (case-insensitive: if the name is 'htmlStrip', 'htmlstrip' can be used when looking up the service).
- "phonetic"
