I am not sure how can this be setup and any help would be very much appreciated.

Lets assume there are 20 Top Level Categories, however I want to limit search function to only Category No. 1 to 16 and want to exclude category no. 17 to 20 from the general search results (these categories will have their individual search function options). Any thoughts on how this can be done?

Thank you.
