• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach kem) or (sach y)) nang ho hoi. hieu va cac duc manh hanh thai ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach kem) OR (sach y)) nang ho hoi. hieu va cac duc manh hanh thai ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach kem) or (sach y)) nang ho hoi. hieu va cac duc manh hanh thai ((cua tre) OR (cuu tre))*".
