Ed, the thread about "pick your stacks carefully" is getting a bit circular and is perhaps not the right forum to ask you a direct question.
I was amazed to learn there are over 640 stacks, and that one man should have 645 of them, so I cannot imagine a better person to ask than you.
I am looking for a filter/search stack which will deliver results based on a string of keywords. For example if I input France, large, mono, illustration, 1936. and automotive, I would get all files (in my case, images) which had ALL or some of those keywords attached to them.
I have not been able to identify such a stack/add-on which will do this. The ones I have looked at and enquired of their developers are either restricted to one keyword, or subtract files which do not have these keywords, leaving those that do, instead of starting with an empty page and adding those that do.
Are you aware of any such stack or add-on? Thanks.
