I'm new to using tsearch2 and am trying to understand why I would want to use an ISpell dictionary before the stemming dictionary. I'd originally hoped that ISpell would suggest corrections for misspelled words as the documents that I will be indexing will contain a lot of spelling mistakes. From what I now understand ISpell dictionaries only recognize properly spelled words. This means that any misspelled word will be handled by the stemming dictionary and usually just passed as is.
1. If I am correct about this then what is the point of using the ISpell dictionary in the first place? 2. Is there a solution for correcting spelling mistakes in the documents you index? I have seen the readme files for pg_trgm, http://www.sai.msu.su/~megera/postgres/gist/, which would allow me to suggest other terms for a query if the misspellings were common enough. I'd rather fix the problem at index time so that querying with the proper term would find any misspelled terms (within reason). ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
