[GENERAL] Full Text Search, avoiding lexemes search

[Daniel Vázquez]

Hi guys!

Full text search, searches by lexemes, this minds that if you are finding
for gato word you are really finding for {gat} lexeme.
I you construct vectors for the words gato, gatos, gata, gatas, all
have the same lexema {gat}
Then the search gato that is to say the search {gat} matches with all
previous vectors.

There some way (configuration, query) to match only for gato and
avoid gatos gata gatas, with FTS ??
Or match only for gato gatos buy no for gata gatas?

Tnks!

Daniel,

just use different fts configuration for search, which doesn't
includes stemmers.
