Exactly - which is just about every time I search! When I'm programming I'm adding new files and definitions constantly.

An alternative method of multi-file search and replace is the Q
command in Dired buffers.  You mark those files in which you wish to
search and replace, and then press Q; the rest is just like with TAGS,
except that no TAGS file is needed.

Thanks - didn't know that. It looks useful.

Back in my Windows days I used an editor called TSE, and I wrote something for it that achieved much the same effect as find-tag and friends without the need to manually update the tags file. It maintained the equivalent of a TAGS file and dynamically updated it as you added new files and definitions. I rather miss it's convenience - maybe one day I'll miss it enough to write an Emacs equivalent :) I suspect that all that wouldbe needed would be to hook something in to rerun "etags" at the appropriate times, so it would be easier than what I wrote for TSE, where I had to implement the whoe etags style functionality. Unless someone else has already done it?
