use Data Assist Search for this.
In Data Assist search, you can set up a Key Word search criteria.
the Keyword search Criteria allows you to define separators. by default, the separators are set up as a coma for OR and space for AND
so searching:
ac, whips
would give search for "ac" OR "whips"
or if you search for:
ac whips
the search would be:
"ac" AND "whips"
