You'll be surprised.
You can force WDF to treat hyphen as a digit if you want to, but you are right that you cannot have both. To change WDF, create a text file, put the following in it, and reference it with the types parameter on WordDelimiterFilterFactory: - => DIGIT I use this functionality to build a special analysis chain for mimetypes. FOR that fieldType, I treat hyphen and underscore as ALPHANUM. Search for "wdfftypes" on this page for more info: https://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters Naturally you have to reindex after making this change. For anyone who doesn't know what that entails: http://wiki.apache.org/solr/HowToReindex Thanks, Shawn
