Hi

This is probably a naive question, but what would I gain from using
snowball and ispell dictionaries in tsearch2, as described here:

http://www.sai.msu.su/~megera/postgres/gist/tsearch/V2/docs/tsearch-V2-intro.html

?

Presumably there is a performance hit associated with doing this (more
from ispell I guess), but what would the benefits be?

Hope someone can enlighten me!

Thanks,

Dominic.
