• Performing a fuzzy search may retrieve terms with similar spellings: thuat sach y nang xa hoi. lieu ((va cai) or (va tham)) ((duc van) OR (duc tan)) thanh va cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach y nang xa hoi. lieu ((va cai) OR (va tham)) ((duc van) OR (duc tan)) thanh va cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach y nang xa hoi. lieu ((va cai) or (va tham)) ((duc van) OR (duc tan)) thanh va cua te".
• Adding a wildcard symbol may retrieve word variants: thuat sach y nang xa hoi. lieu ((va cai) or (va tham)) ((duc van) OR (duc tan)) thanh va cua te*.
