I am looking for a quick solution to expand queries so they will look for synonms as well. The same way WordNet is doing - it will looks for other words that mean the same as written in the query.
So Synonyms and WordNet are better categories to describe what I need. Any idea? Currently what I do, is expending the query in my own code - for every word in the query I also add the 10 most close words to that one and parse it to the query parser. It takes a bit time and I wondered whether I am missing something and it can be done in a better way.
