I use search boxes throughout my site with this code-
<form action="/catalogsearch/result/" method="get">
And everything works great. I am now trying to use this same method with advanced search. The purpose is to only search within a single attribute. In my case this url works great-
The problem I am running into is if I try to use this code-
<form action="/catalogsearch/advanced/result/?manufacturer=26" method="get">
It doesn't work. It seems like it strips ?manufacturer=26, but even if it didn't strip off the ? I don't think a url would work with two separate ? anyway. Anyone have any idea to fix this? Or a different idea to create a search by an attribute?
