• Performing a fuzzy search may retrieve terms with similar spellings: thuat lanh y nang ma hoi. hieu van cao duc ((van anh) or (van thanh)) vai ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat lanh y nang ma hoi. hieu van cao duc ((van anh) OR (van thanh)) vai ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat lanh y nang ma hoi. hieu van cao duc ((van anh) or (van thanh)) vai ((cua tre) OR (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: thuat lanh y nang ma hoi. hieu van cao duc ((van anh) or (van thanh)) vai ((cua tre) OR (cuu tre))*.
