My previous team studied allowing similar queries, and we didn't see anything so easy to interpret into a query. In testing, users typed in a lot of strings that couldn't be interpreted (by machine or human), or which were ambiguous. It may be that people have gotten used to Google/Bing accepting crap queries and still showing a decent rezult. But, I suspect the main problem is they couldn't explain what they wanted to a human, at least not without considerable conversation.
