• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((((theo sach) OR (te sach))) or (chieu sach)) - hanh hang ca dong cong dan phan tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((((theo sach) OR (te sach))) OR (chieu sach)) - hanh hang ca dong cong dan phan tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((((theo sach) OR (te sach))) or (chieu sach)) - hanh hang ca dong cong dan phan tu*".
