• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ty ((nang xa) OR (nang ma)) hoi. hieu qua cac xuc va dinh ((ve cua) OR (te cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ty ((nang xa) or (nang ma)) hoi. hieu qua cac xuc va dinh ((ve cua) OR (te cua)) tre*".
