Computer Name Search using And/Or

In central, when searching for computers, it used to use an "AND" between words by default so I could put something like   SUPER ISP   and it would find all entries that included both SUPER and ISP in the computer name.    Now it seems to be using an  "OR" between words so it is finding me all entries that have either an ISP in the name or SUPER in the name.   Is this a setting I mistakenly changed or something that was changed with Central?
