Multiple Search in SEPM

1. When a search is done using Computer name.. Im able to get the result

2. When a search is done using a 2nd computer name.. I still get the result

3. When I search both in one attempt, the result is cannot find...

Why? Is this is the behaviour of SEPM?

Note: I have tried Computer name in the first row and then used IP to search in the 2nd row...

**Confused**
