Namespace Lucene.Net.Analysis.Phonetic

Analysis components for phonetic search.

Classes

BeiderMorseFilter

TokenFilter for Beider-Morse phonetic encoding.

This is a Lucene.NET EXPERIMENTAL API, use at your own risk

BeiderMorseFilterFactory

<fieldType name="text_bm" class="solr.TextField" positionIncrementGap="100">
  <analyzer>
    <tokenizer class="solr.StandardTokenizerFactory"/>
    <filter class="solr.BeiderMorseFilterFactory"
       nameType="GENERIC" ruleType="APPROX" 
       concat="true" languageSet="auto"
    </filter>
  </analyzer>
</fieldType>

DoubleMetaphoneFilter

Filter for DoubleMetaphone (supporting secondary codes)

DoubleMetaphoneFilterFactory

Factory for DoubleMetaphoneFilter.

<fieldType name="text_dblmtphn" class="solr.TextField" positionIncrementGap="100">
  <analyzer>
    <tokenizer class="solr.WhitespaceTokenizerFactory"/>
    <filter class="solr.DoubleMetaphoneFilterFactory" inject="true" maxCodeLength="4"/>
  </analyzer>
</fieldType>

PhoneticFilter

Create tokens for phonetic matches. See the Language namespace.

PhoneticFilterFactory

Factory for PhoneticFilter.

Create tokens based on phonetic encoders from the Language namespace.

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.
