• Performing a fuzzy search may retrieve terms with similar spellings: ((te cac) or (te cao)) ky lang hoa hoi. hieu va tham soc va hanh vi ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te cac) OR (te cao)) ky lang hoa hoi. hieu va tham soc va hanh vi ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te cac) or (te cao)) ky lang hoa hoi. hieu va tham soc va hanh vi ((cua tre) OR (cuu tre))*".
