Thanks Ivan , Yes I too found the same by referring "account_move_line" object... However I came over across 2 kinds of select parameters, i.e "select=1" means Basic Search, "select="2" means Advance Search... Any idea what exactly is the difference... In database level I see no difference between these two indexes..

I think that has something to do with whether the field will be displayed as search criteria by default in a search view. If select=1, a default search view will have the field added. At least that is what I've experienced with v6. I'm not sure whether it is still valid for v7 and v8.

Ya ok, even I feel the same.. thanks anyway :)
