"All Categories" option for keywords search was implemented in build 797 to appear always.
In older releases it appears only if all your categories have the same fields set, i.e. when you don't use category specific ad fields.
If you'll just add 'All Categories' in HTML with id=0 the search will not produce accurate results in most cases.
Hi Hawk. I have version 797, but "All Categories" does not appear as the default setting for search. Nor does it appear as if it can be added through the Admin. What steps should I take to support search across all categories?
Thank you.
