public class TypeAsSynonymFilterFactory extends TokenFilterFactory
TypeAsSynonymFilter
.
In Solr this might be used as such
<fieldType name="text_type_as_synonym" class="solr.TextField" positionIncrementGap="100"> <analyzer> <tokenizer class="solr.UAX29URLEmailTokenizerFactory"/> <filter class="solr.TypeAsSynonymFilterFactory" prefix="_type_" synFlagsMask="5" ignore="foo,bar"/> </analyzer> </fieldType>
If the optional prefix
parameter is used, the specified value will be prepended
to the type, e.g. with prefix="_type_", for a token "example.com" with type "<URL>",
the emitted synonym will have text "_type_<URL>". If the optional synFlagsMask is used
then the flags on the synonym will be set to synFlagsMask & tokenFlags
. The
example above transfers only the lowest and third lowest bits. If no mask is set then
all flags are transferred. The ignore parameter can be used to avoid creating synonyms for
some types.
