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