I have the same problem, It was working correctly on another computer, but not this one. Here is a screen shot (with confidential info blacked out): I typed in "rev" to find my "review" tag. The tag is listed in the tag list and has 12 notes. I have it selected. Now, if I click on this, it should do a search just for the "review" tag. Instead, my search is still just the "rev" that I have actually typed in.
