allen,
consider a search box such as google.com. it doesn't need to state that
i can quote words to form a phrase, but i can. allowing quotes phrases
doesn't mean you need to explain this up front. however, suppose a user
did want to do this? what's the first thing they'd try? quotes.
regardless, i don't really think this is so complicated for a user to
understand:
"enter tags separated by spaces. use quotes for multi-word tags".

So, consider for example, if you had to explain how to enter tags to
your parents or some other very non-technical people. I think it's
far easier to explain #1 and simply say "enter any tags you want,
separated by spaces. if you have multi word tags then use underscores
to join the words." rather than trying to instruct them on how to
group phrases with quotes and then creating a way for them to actually
mess up the process if they did something like this ... 'tag1 tag2
"tag phrase' and forgot the end quote.
