• Performing a fuzzy search may retrieve terms with similar spellings: thuat san y nang xa hoi. ((hieu ve) or (hieu va)) ((cau thuc) OR (cau truc)) dan tinh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat san y nang xa hoi. ((hieu ve) OR (hieu va)) ((cau thuc) OR (cau truc)) dan tinh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat san y nang xa hoi. ((hieu ve) or (hieu va)) ((cau thuc) OR (cau truc)) dan tinh vi cua te".
• Adding a wildcard symbol may retrieve word variants: thuat san y nang xa hoi. ((hieu ve) or (hieu va)) ((cau thuc) OR (cau truc)) dan tinh vi cua te*.
