Search by phrase of 2 words or more hack?

[mvigod]

Is there a way to search by phrase such as "great hacks" to find all occurences of those words together rather than every single post that contains both of the words whether together or not?

If not is this a hack that can be done or would the entire search index have to be redesigned to allow for phrases as opposed to single words?

I was thinking the same thing, anyone care to comment?

Thanks,
