• Performing a fuzzy search may retrieve terms with similar spellings: ho ((((chieu xanh) OR (chieu sach))) or (hieu lang)) - hanh trang vat dung cong dan van ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((((chieu xanh) OR (chieu sach))) OR (hieu lang)) - hanh trang vat dung cong dan van ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((chieu xanh) OR (chieu sach))) or (hieu lang)) - hanh trang vat dung cong dan van ban*".
