• If you are trying to use Boolean operators, they must be ALL CAPS: te cach tu nano xa hoi. ((hieu van) OR (hieu va)) cam xuc ban ((hang di) OR (hang dien)) cau tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te cach tu nano xa hoi. ((hieu van) or (hieu va)) cam xuc ban ((hang di) OR (hang dien)) cau tre".
• Adding a wildcard symbol may retrieve word variants: te cach tu nano xa hoi. ((hieu van) or (hieu va)) cam xuc ban ((hang di) OR (hang dien)) cau tre*.
