: This is a fairly basic synonyms question: how does synonyms handle stemming?
it's all a question of how your analysis chain is configured forh te field type. if you have your stemming filter before your synonyms filter, then the synonyms.txt file needs to map the *stems* of hte synonyms. if you have stemming after synonyms, then you need to have mappings for *all* of the roots. i encourage you to experiement with differnet settings and look at the analysis.jsp tool to see the effects. -Hoss
