PDM Search doesn't narrow results searching on two variables

Hi all,

Wondering if anyone has a suggestion on what's happening:

 

Searching on two variables "partno" and "description" is not narrowing the results but seems to actually be ADDING to the results

 

In the screen below, searching on "4-" in partno, and "10-32" in description shows configurations that don't have "10-32" in the description, but is showing 4- results....I would expect to only see configs that have both 4- in partno, and 10-32 in description.

 

What am I missing?

Thanks in advance for anyone's replies.
