• If you are trying to use Boolean operators, they must be ALL CAPS: thu san ky sang mai hai. hieu su chat ((xuc va) OR (tuc va)) hanh vi ((cua te) OR (cua tuc)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu san ky sang mai hai. hieu su chat ((xuc va) OR (tuc va)) hanh vi ((cua te) or (cua tuc))".
