• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty xang xa hoi. ((hieu ve) or (thien van)) ((cac xuc) OR (cac nuoc)) va danh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty xang xa hoi. ((hieu ve) OR (thien van)) ((cac xuc) OR (cac nuoc)) va danh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty xang xa hoi. ((hieu ve) or (thien van)) ((cac xuc) OR (cac nuoc)) va danh vi cua te".
• Adding a wildcard symbol may retrieve word variants: su sach ty xang xa hoi. ((hieu ve) or (thien van)) ((cac xuc) OR (cac nuoc)) va danh vi cua te*.
