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