• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sach) or (thuat lap)) ky lang xa hoi. hieu vien cho xu ((va hanh) OR (van hanh)) vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (thuat lap)) ky lang xa hoi. hieu vien cho xu ((va hanh) OR (van hanh)) vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) or (thuat lap)) ky lang xa hoi. hieu vien cho xu ((va hanh) OR (van hanh)) vi cua te".
• Adding a wildcard symbol may retrieve word variants: ((thu sach) or (thuat lap)) ky lang xa hoi. hieu vien cho xu ((va hanh) OR (van hanh)) vi cua te*.
