Tag search logic

[truefire]

I would like to be able to search for all entries that have at least one of a number of tags.

For example, at present, I can type in "Tag1 Tag2" and I will be shown entries that have both Tag1 and Tag2. I would like to be able to input something like "Tag1 OR Tag2" and get any entries that have either Tag1 or Tag2, but not necessarily both.

Seconded! I just found a need for or-search myself.
