• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky tang xa hoi. ((hieu ve) or (hieu va)) cam xuc ban anh hai ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky tang xa hoi. ((hieu ve) OR (hieu va)) cam xuc ban anh hai ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky tang xa hoi. ((hieu ve) or (hieu va)) cam xuc ban anh hai ((cua tre) OR (cua te))".
• Adding a wildcard symbol may retrieve word variants: tu sach ky tang xa hoi. ((hieu ve) or (hieu va)) cam xuc ban anh hai ((cua tre) OR (cua te))*.
