• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu sach) OR (chieu sang)) - thanh ((trung cap) or (truong ca)) hang cong van thanh mau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (chieu sang)) - thanh ((trung cap) OR (truong ca)) hang cong van thanh mau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) OR (chieu sang)) - thanh ((trung cap) or (truong ca)) hang cong van thanh mau*".
