• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ky) OR (sac ky)) lang ((mai khoi) or (cac khoi)). hieu ve cham duc manh hang tai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sac ky)) lang ((mai khoi) OR (cac khoi)). hieu ve cham duc manh hang tai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) OR (sac ky)) lang ((mai khoi) or (cac khoi)). hieu ve cham duc manh hang tai cuu tre".
• Adding a wildcard symbol may retrieve word variants: su ((sach ky) OR (sac ky)) lang ((mai khoi) or (cac khoi)). hieu ve cham duc manh hang tai cuu tre*.
