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,simple
But 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
Regards,
Oleg
