• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chiet tach) or (((chieu sang) OR (chieu sach)))) - anh nang cua hang cong manh toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chiet tach) OR (((chieu sang) OR (chieu sach)))) - anh nang cua hang cong manh toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chiet tach) or (((chieu sang) OR (chieu sach)))) - anh nang cua hang cong manh toan cau*".
