how to set up prestashop search preferences to give max priority to product name ( for AJAX search )

[ezakimak]

Hi,

As the subject says, I need advice setting this up correctly,
The fact is that typing the same words in the block search ( with AJAX ) , gives different results depending on the language selected in FO, what I would like to do is give the product name the max priority for searches, the products name in our shop is the same in all languages, I have tried different word wieght combinations in BO but no good results, perhaps someone here could point me to the right direction

thanks

Hugh

p.s. and of course i have rebuilt the entire index
