Jed, I too, took this request as an opportunity to test my growing knowledge of TiddlyWiki, I do not have the skills, or perhaps tiddlywiki does not have the features to finish the approach I came up with but given your interest I thought I would pass it on to you.
One approach is as follows (Test tags called On and Off) Determine the sum of characters required for the two tags +1 =Tagslength thus length of the tag field if only tagged with these two tiddlers Use a List to extract only tiddlers tagged with the required tiddlers <$list filter="[tag[On]] +[tag[Off]]"> Then throw away all cases where tags field in longer than Tagslength What remains is what was needed. Notes: This should be extensible to any number of tags Opinion I suspect Diego could have designed his TiddlyWiki such that this was not needed, the fact he does not know what other tags to exclude, or must exclude, suggests something astray in his wiki's design. Note: I am prepared to prove this if Diego wants my help, not code but design. As someone climbing the TiddlyWiki learning mountain, I find my path impeded by two things; 1. The Complexity and context sensitive nature of references. 2. The Gaps between what may need to be done and what can be done (especially in light of my ignorance) I am not ignorant of coding with expertise in at least two languages, but I admit I am struggling to make progress as rapidly as I expect (although I am learning quickly). Either I am loosing my faculties or TiddlyWiki is resisting my learning it. In TiddlyWiki we should be able to do any primitive set manipulation, queue manipulation, any basic database lookup, basic counts and structures like do until, decisions, cases etc... and do this on any TiddlyWiki object like tiddlers, Tags, Fields. Until this is the case it will be hard to learn, because we can waist a lot of time looking for things that do not exist. (or are undocumented). I value your contribution to addressing the gaps.
