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