• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky nang xa hoi. hieu ve cham xuc va ((han tai) or (van tai)) ((va thieu) OR (va hieu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang xa hoi. hieu ve cham xuc va ((han tai) OR (van tai)) ((va thieu) OR (va hieu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang xa hoi. hieu ve cham xuc va ((han tai) or (van tai)) ((va thieu) OR (va hieu))".
