Also, if you install
http://www.TiddlyTools.com/#MatchTagsPlugin
then you can use full boolean logic expressions (and/or/not) for tag
matching. Instead of specifying just a single tag value in the
filter, e.g., [tag[tagvalue]], you can filter for complex combinations
of tag values, like this:
[tag[tag1 AND tag2 OR (tag3 and NOT tag4) OR tag5]
and you can use "-" as a special value to select *untagged* tiddlers,
e.g.:
[tag[tag1 OR -]]
you can also use regular expression (text pattern) syntax to specify
tag values:
[tag[(foo|bar).*]]
will match any tags that start with "foo" or "bar".
