• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (so sach)) lo lang van hoc. hieu qua ((cau phuc) OR (huu phuc)) va hanh di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) lo lang van hoc. hieu qua ((cau phuc) OR (huu phuc)) va hanh di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (so sach)) lo lang van hoc. hieu qua ((cau phuc) OR (huu phuc)) va hanh di cua te".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (so sach)) lo lang van hoc. hieu qua ((cau phuc) OR (huu phuc)) va hanh di cua te*.
