I search for questions through questions/tagged using the OR operator.  Here's a screen-shot that shows the problem:

![alt text][1]

My "Interesting tags" selections are not visible but match the query as visible in the upper right.

 - First visible question has *three* tags that I have selected as interesting tags, no highlight.
 - Second visible question has *two* interesting tags, no highlight.
 - Thirst visible question has *one* interesting tag, highlighted.

At least here, it is doing the *exact* opposite of what it should do.  I assume it has something to do with the OR operator, if it is easier to fix by just highlighting them all then please don't hesitate to fix it that way.
