It sounds like what you want is either MatchTagsPlugin by Eric Shulman (The TiddlyTools guy) or YourSearchPlugin by Udo Borkowski.

Both let you do full operator-enhanced tag searches but their syntax and other features differ.

MatchTagsPlugin lets you set up a new search field which displays its results in a new tiddler in a configurable format and will search only tags using a syntax like this:

excel AND (macro OR script) AND NOT virus

If the provided interfaces don't do it for you, take a look at what I did using InlineJavascriptPlugin.

YourSearchPlugin modifies the existing search field to support a richer query syntax (and, optionally, a new results popup) and you can specify that a given entry should only match tags by prefixing it like this:

#excel (#macro or #script) not #virus

You could also poke around on TiddlyHub to see if anything else might meet your needs.

I recently encountered the same problem, here is how I solved it:

1) Create a new-tiddler-button that creates each tiddler with a unique ID.

For creating a custom new-tiddler-button see for example Stephan Hradek's example on http://tiddlystuff.tiddlyspot.com/.

You can create a javascript macro that returns a unique id and uses this unique id as field value

2) Referencing From now on, reference tiddlers via

{{{ [field:id[ <yourID> ]!has[draft.of]] }}}

or <$list filter=[field:id[ <yourID> ]!has[draft.of]] />
