• If you are trying to use Boolean operators, they must be ALL CAPS: thu sang ky ((nang x) OR (((nang ma) OR (sang ma)))) hoi. nhin viet cac xuc va trinh via cua tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sang ky ((nang x) or (((nang ma) OR (sang ma)))) hoi. nhin viet cac xuc va trinh via cua tu~".
• Adding a wildcard symbol may retrieve word variants: thu sang ky ((nang x) or (((nang ma) OR (sang ma)))) hoi. nhin viet cac xuc va trinh via cua tu*.
