From "SubSearch within a search?"
"After sub-searches, I then added check-boxes per search-result for use/not-use. This is especially handy, where the search engine can't distinguish, but you want a very tight population for the next sub-search. And it's heaven-sent for exporting and notes (I allow attaching notes to search results)."
Talks of check box. What is the best way to choose what you wish to use, and delete or abandon what you do not from a search?
