• Performing a fuzzy search may retrieve terms with similar spellings: theo chieu sach - hanh trung cap ((((ban nong) OR (ban cong))) or (ban nang)) dang thanh chu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - hanh trung cap ((((ban nong) OR (ban cong))) OR (ban nang)) dang thanh chu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - hanh trung cap ((((ban nong) OR (ban cong))) or (ban nang)) dang thanh chu*".
