• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho hieu) OR (ho chieu)) lang - hanh mang cua thong dong thanh ((san tap) OR (dan tay))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho hieu) OR (ho chieu)) lang - hanh mang cua thong dong thanh ((san tap) or (dan tay))~".
• Adding a wildcard symbol may retrieve word variants: ((ho hieu) OR (ho chieu)) lang - hanh mang cua thong dong thanh ((san tap) or (dan tay))*.
