Steven Weldler posted a possible new Google web search feature on Google+. If you search for a long tail keyword and Google can't find too many matches, Google will show you "results for similar searches." Now that isn't new.
What appears to be new, is that it shows "more results for X" and crosses off keywords that it didn't match on.
For example, a search for [long island man jump stan] returns a result from the New York Times and under it shows "More results for long island man jump stan."
Here is a screen shot:
I don't believe I've seen this before.
In any event, this can be useful in terms of a keyword research tool for SEOs and marketers.
