Hi!I'm using postgres 8.4.3 and try to get stemming/ wrong word correction working.I already installed the myspell dictionaries using apt-get and created postgres dictionaries like this:Fulltext search configuration ?public.english_ispell? Parser: ?pg_catalog.default? Token | Dictionaries -----------------+------------------------------------ asciihword | english_ispell,english_stem,simple asciiword | english_ispell,english_stem,simple email | simple file | simple float | simple host | simple hword | english_ispell,english_stem,simple hword_asciipart | english_ispell,english_stem,simple hword_numpart | simple hword_part | english_ispell,english_stem,simple int | simple numhword | simple numword | simple sfloat | simple uint | simple url | simple url_path | simple version | simple word | english_ispell,english_stem,simpleBut when I do, for example, SELECT to_tsvector('english_ispell', 'gitar') the result is only:'gitar':1 Shouldn't the word be corrected to 'guitar'?
english_ispell dictionary is a morphology kind of dictionary ! Read docs. Also, simple dictionary will never invoked, since english_stem dictionary recognizes everything !
SELECT plainto_tsquery('english_ispell','gitar') doesn't work neither:
'gitar'
Better, use ts_debug() function or ts_dict() for testing.
Thanks, Corin
