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