I don't really know if this qualifies as a bug, but it is rather odd. I was doing a search for certain words in the Book of Job in HMT-W4. I set up a range for Job and set the search thus:

When I then search for the word נאם (which doesn't actually appear in Job), the search automagically switches to verses and displays Nahum (because the Hebrew is turned into "nam").
I can understand why this happens, but it still seems a little odd!
