Search words with - minus sign

[wallybz]

Hi all,

I have a shop with more than 100.000 products. I just migrated from 1.4 to 1.5.

The search of words that contains the "-" minus sign does not work anymore.

 

Prestashop stores single words in the database:

EPSON INKJET MULTIFUNCTION XP-700 is taking 4 records in version 1.4:

EPSON - INKJET - MULTIFUNCTION - XP700

If I search "XP-700" the product is found

 

In version 1.5 there are only 3 records:

EPSON - INKJET - MULTIFUNCTION

and so searching for "XP-700" shows no results.

 

I tried also with a clean 1.5 installation but no way.

 

Any idea?
