• Performing a fuzzy search may retrieve terms with similar spellings: te sach thu hang x hoi. hieu qua ((cam xuc) or (chat xuc)) ((va hanh) OR (van hanh)) dai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thu hang x hoi. hieu qua ((cam xuc) OR (chat xuc)) ((va hanh) OR (van hanh)) dai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thu hang x hoi. hieu qua ((cam xuc) or (chat xuc)) ((va hanh) OR (van hanh)) dai cuu tre*".
