• If you are trying to use Boolean operators, they must be ALL CAPS: vu van ky ((nang xa) OR (nang ma)) hoi. hieu viec ((cam xuc) OR (chat xuc)) va hanh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu van ky ((nang xa) OR (nang ma)) hoi. hieu viec ((cam xuc) or (chat xuc)) va hanh vi cua te*".
