I log the search phrases the users on my site are using to search, and review them regularly. Based on that i add synonyms for certain phrases to help increase the relevant results. The reason i don't have the synonym filter at index time is because i can't re-index whole/portion of data everytime i add synonyms because my index is huge. Any suggestions on how to overcome this?
