## org.apache.lucene.analysis.phonetic
Class PhoneticFilterFactory

    java.lang.Object
      org.apache.lucene.analysis.util.AbstractAnalysisFactory
          org.apache.lucene.analysis.util.TokenFilterFactory
              org.apache.lucene.analysis.phonetic.PhoneticFilterFactory

All Implemented Interfaces:
  ResourceLoaderAware

    public class PhoneticFilterFactory

extends TokenFilterFactory
implements 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), or "ColognePhonetic" (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.

       <analyzer>
         <tokenizer class="solr.WhitespaceTokenizerFactory"/>
         <filter class="solr.PhoneticFilterFactory" encoder="DoubleMetaphone" inject="true"/>
       </analyzer>
     </fieldType>
