• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((can ky) OR (dan ky)) ((nang mai) OR (lang mai)) hoi. hieu ve chat xuc ban hanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((can ky) or (dan ky)) ((nang mai) OR (lang mai)) hoi. hieu ve chat xuc ban hanh vi cua te".
