Well, if you check how Google approaches it, the use double quotes to indicate a phrase with a blank in it.

e.g. http://www.google.com/search?q=%22horse+riding%22

Any delimiter which makes for valid/clean URLs and isn't allowed to occur in a tag would work. It is unlikely that a tag would have opening and trailing quotes. I'd prefer to use a comma because it is slightly more readable and slightly cleaner. Of course, that means we have to restrict the use of commas in tags which sounds acceptable to me (but can be debated): ?q=horse+riding,beach,sunset -- Dries Buytaert :: http://www.buytaert.net/
