• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ty) or (cac ky)) lang xa hoi. ((hieu van) OR (hieu va)) cau trang va hanh dao cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (cac ky)) lang xa hoi. ((hieu van) OR (hieu va)) cau trang va hanh dao cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) or (cac ky)) lang xa hoi. ((hieu van) OR (hieu va)) cau trang va hanh dao cua te".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ty) or (cac ky)) lang xa hoi. ((hieu van) OR (hieu va)) cau trang va hanh dao cua te*.
