• Performing a fuzzy search may retrieve terms with similar spellings: theo ((chieu sang) OR (hieu lang)) - hanh thang van duong vuong ((anh toan) or (thanh toan)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu sang) OR (hieu lang)) - hanh thang van duong vuong ((anh toan) OR (thanh toan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sang) OR (hieu lang)) - hanh thang van duong vuong ((anh toan) or (thanh toan)) cau*".
