Synonym Search Using Sphinx

Question

Has somebody written a morphology engine for synonyms on sphinx. Or is the best bet still to create a word forms dictionary which declares all my synonyms. Also how will this affecting stemming. In the documentation it states:

stemming is not applied to words found in the forms list

Does this mean that if I have defined running > run in my wordform that runs will not be stemmed to run because run appears in my word forms list?

Answer 1

You can create synonyms in mongo or mysql for example, and do query preporcessing, so when somebody do search with:

Cola

you will change the query to:

(cola|pepsi|sprite)

which allow you to do morphology search on those words, because stemming doesn't apply to word-forms as you have mentioned.
