Let admin create more than one search

I love that you can choose which vocabs to include in a search, but if a site has a need to restrict trip search in one area, it can't use the search generally. For example, trip search is great for a job search (though location features would help :), a user clicks "find jobs link" and has only the "Job Sector" and "Salary" vocabs available for their search. Admin also wants to use trip search for general site searching, but can't now because of the "job search" they set up. Allowing multiple restricted searches (restricting by both node type and vocab/terms) would make this an even more valuable and flexible search engine. One site could have product searches, job searches, content searches, etc.
