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