Quicksearch module search by ref

Hello.

I would like to know how to modify the OS module Quicksearch for that instead of searching by location,I can search by reference.

thx

Hi Daniel,
Sorry for misunderstand in the ticket. I have just read you question again, and i found i answered you wrong.
In fact, even you enter the ref number into the inputbox, the system still search through both address and property's fields like name, ref number ..etc
Thanks
