• If you are trying to use Boolean operators, they must be ALL CAPS: thu san ((ky dang) OR (ky danh)) lai hoi. hieu su chat ((xuc va) OR (luc va)) hanh tai cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu san ((ky dang) OR (ky danh)) lai hoi. hieu su chat ((xuc va) or (luc va)) hanh tai cua tu".
