• Performing a fuzzy search may retrieve terms with similar spellings: su sac ky nang xa hoi. hieu vien cac xuc ((ngan hang) or (van anh)) vi ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang xa hoi. hieu vien cac xuc ((ngan hang) OR (van anh)) vi ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang xa hoi. hieu vien cac xuc ((ngan hang) or (van anh)) vi ((cua tre) OR (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: su sac ky nang xa hoi. hieu vien cac xuc ((ngan hang) or (van anh)) vi ((cua tre) OR (cuu tre))*.
