Pardon my ignorance here. I have tried to do a search using some of the search operators found at http://wiki.logos.com/Detailed_Search_Help.
Instead of operating, the operators seems to be a part of the search. Here's what I'm doing (fwiw, it happened to me on both Win and Mac today):
(finger OR hand) WITHIN 2 WORDS God
Here are the results. I'm looking for "finger of God" or "hand of God", but I'm finding results that have the word "within" in them.

Thanks,
Bill
