Specify multiple categories for category search?
Is it possible to specify multiple categories to search in when doing a category restricted search like so:
<search:setCategory category="cat1"/>
<search:setSearchAll searchAll="false"/>
This sample searches only in "cat1". Now is it somehow possible to specify multiple categories with the setCategory tag? If so, how? If not, any other possibility to perform a multi-category search?
thanks in advance!
