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