• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty xang ((ma hoa) OR (xa hoi)). hieu ve cac xuc va hanh ((thai cua) OR (tri cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty xang ((ma hoa) or (xa hoi)). hieu ve cac xuc va hanh ((thai cua) OR (tri cua)) te".
• Adding a wildcard symbol may retrieve word variants: tu sach ty xang ((ma hoa) or (xa hoi)). hieu ve cac xuc va hanh ((thai cua) OR (tri cua)) te*.
