Two key words in Quick Search

User type two keywords in Quick Search, but the grid still search two keywords like one.
for example: I input “Aword Bword” in quick search, I would like to search the records that contained Aword and Bword same time. The system only shows the records include “Aword Bword”, but can’t show the records like “Aword XXXXXX Bword” .
Now I ask the user to use % instead of space (“Aword%Bword”). It works fine, but it wired.
Is there some good way just let user input words like normal “Aword Bword”?

Thanks.
