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