• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (te sach)) ky nang xa hoi. sieu van hai xu ((va thanh) or (va tinh)) lap cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ky nang xa hoi. sieu van hai xu ((va thanh) OR (va tinh)) lap cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) ky nang xa hoi. sieu van hai xu ((va thanh) or (va tinh)) lap cua viet".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (te sach)) ky nang xa hoi. sieu van hai xu ((va thanh) or (va tinh)) lap cua viet*.
