Apache Solr Reference Guide Covering Apache Solr 6.0

In: "cat concatenate catycat"
Tokenizer to Filter: "cat", "concatenate", "catycat"
Out: "dog", "condogenate", "dogycat"
Example:
More complex pattern with capture group reference in the replacement. Tokens that start with non-numeric
characters and end with digits will have an underscore inserted before the numbers. Otherwise the token is
passed through.
In: "cat foo1234 9987 blah1234foo"
Tokenizer to Filter: "cat", "foo1234", "9987", "blah1234foo"
Out: "cat", "foo_1234", "9987", "blah1234foo"
Phonetic Filter
This filter creates tokens using one of the phonetic encoding algorithms in the org.apache.commons.codec.
language package. For more information, see the section on Phonetic Matching.
Factory class: solr.PhoneticFilterFactory
Arguments:
encoder: (required) The name of the encoder to use. The encoder name must be one of the following (case
insensitive): " DoubleMetaphone", " Metaphone", " Soundex", " RefinedSoundex", " Caverphone" (v2.0), " CologneP
honetic", or " Nysiis".
inject: (true/false) If true (the default), then new phonetic tokens are added to the stream. Otherwise, tokens
are replaced with the phonetic equivalent. Setting this to false will enable phonetic matching, but the exact
spelling of the target word may not match.
maxCodeLength: (integer) The maximum length of the code to be generated by the Metaphone or Double
Metaphone encoders.
Example:
Default behavior for DoubleMetaphone encoding.
