SynonymSearch 1.8.1 The SynonymSearch module is providing custom categorization of arbitrary content types.

Synonym search will extend Lucene search to allow search on all indexed content (including but not limited to content items, comments, blogs, tags and taxonomy) with multiple keywords. It does not require a user to edit each content item. Further the user can view results in order of relevance and filter out the content for the irrelevant keywords on the front end.
