• If you are trying to use Boolean operators, they must be ALL CAPS: thu cach thu sang ma hoi. hieu ((ve cam) OR (ve cham)) loc va hanh ((gia cua) OR (giau cua)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu cach thu sang ma hoi. hieu ((ve cam) OR (ve cham)) loc va hanh ((gia cua) or (giau cua)) triet*".
