for index chinese words, TSearch2 OR Lucene? My mates said to me that Lucene is more effifent
because of its way of "Inverse Order OF Idexing",and "The GiST Tree is well for larting lan but doesn't for chinese lan(also ineffifent for Japanese lan)"。
I only know that GiST is also "Inverse Order OF Idexing",but of course it is a tree NOT as lucene does
What is your suggestion?Which is More suit for Chinese(Janpanese) ,TSearch2 OR Lucene?(Besides other components)

The limit is about 10^5 - 10^6 rows in practice. -- Teodor Sigaev E-mail: teodor@sigaev.ru WWW: http://www.sigaev.ru/
