Full Text Search, avoiding lexemes search

[Daniel Vázquez <daniel2d2art@xxxxxxxxx>]

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!
