• Performing a fuzzy search may retrieve terms with similar spellings: su sac ky lang ha noi. hieu van tham sac van ((hanh vai) or (hanh va)) ((cua tu) OR (cua su))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky lang ha noi. hieu van tham sac van ((hanh vai) OR (hanh va)) ((cua tu) OR (cua su)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky lang ha noi. hieu van tham sac van ((hanh vai) or (hanh va)) ((cua tu) OR (cua su))".
• Adding a wildcard symbol may retrieve word variants: su sac ky lang ha noi. hieu van tham sac van ((hanh vai) or (hanh va)) ((cua tu) OR (cua su))*.
