Title: Check for blank before search

It doesn't look like this is actively maintained, but I like this solution over any others because it does not rely on simply filling in autocomplete and doesn't get in the way. I saw there was a pull request to specify a number of characters before search, which is a great idea. However, assuming that its optional, it would make sense to check for blanks before sending the query.
