My brain must be dead, because while I read the book, I am having trouble devising a solution to this problem.
I would like to include a button on a page of query results that allows users to filter the results to those that match only certain criteria. I realize that it's not a good idea to run a whole new query just for this filtering, so I have been trying to look for a solution, but to no avail.
Any tips? I'm sorry for being vague, I'd just rather not give away too much about the site's structure. Thank you!
