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