We have two main channels: products and blog. When a user enters a search term, if we find results in the primary channel (as indicated by the search_type cookie), we display the results and we're done. If we don't find results, then we need to let the user know we haven't found anything in products, but we did get n hits in blog.
So, I'm wondering about other ways of doing alternate searches. Any recommendations? (I should have sent out this question a long time ago.) Thanks for your help.
