public interface TokenFilterFactory
TokenFilterFactory
creates a
TokenFilter
to transform one TokenStream
into another.
TokenFilterFactories are registered for FieldType
s with the
IndexSchema
through the schema.xml
file.
Example schema.xml
entry to register a TokenFilterFactory
implementation to transform tokens in a field of type "cool"
<fieldtype name="cool" class="solr.TextField"> <analyzer> ... <filter class="foo.MyTokenFilterFactory"/> ...
A single instance of any registered TokenFilterFactory is created via the default constructor and is reused for each FieldType.
