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