Peter, Tags are really good for instant relationships and are there out of the box. If you use too many different tags we call this "polluting the tag space" because there a too many tags and they become unwieldy to use, before they perform badly.
If you find your wiki slowing or with too many tags there are a range of ways to move tags to fields. For example say you had a tag for tasks then 5 tags for status have a field called tiddler-type = Task, and a field status = new/wip/done etc... Now rather than use tag filters use field filters. In fact they can read very nicely, for example this is a valid filter for use in a tiddler tagged viewTemplate `[all[current]tiddler-type[task]` Or `[all[current]tiddler-type[task]!status[new]]` Personally I use very few tags even for complex solutions, because I drive my design into fields rather than use tags. This allows my tags to remain free for ad hoc categories. Unless you design fields to contain multiple values they are useful in so far as a field eg status, can only have one value at a time, if using tags when you tag a task as done, you may also need to remove the tag new. Also one thing you may come to realise is every filter starts by considering most if not all tiddlers and the filter reduces them eg; `[haschanged[]]` considers all tiddlers then extracts those that have changed. See also https://tiddlywiki.com/#Filter%20Run in some ways it shows you how tiddlywiki already performs well with titles, because most filters consider every tiddler title already. - If you say [tag[done]] it needs to check every tiddlers tag field and if it contains done (along with other tags) - If you say [status[done]] it needs to check every tiddlers status field and if it *equals done (a slightly simpler test)* Titles, tags and other elements are stored in working indexes in memory to facilitate this performance.
