• Performing a fuzzy search may retrieve terms with similar spellings: thu sach v ((nang xa) OR (lang xa)) hoi. hieu qua cac xuc van anh ve ((cua triet) or (su viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach v ((nang xa) OR (lang xa)) hoi. hieu qua cac xuc van anh ve ((cua triet) OR (su viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach v ((nang xa) OR (lang xa)) hoi. hieu qua cac xuc van anh ve ((cua triet) or (su viet))".
• Adding a wildcard symbol may retrieve word variants: thu sach v ((nang xa) OR (lang xa)) hoi. hieu qua cac xuc van anh ve ((cua triet) or (su viet))*.
