• Performing a fuzzy search may retrieve terms with similar spellings: ho lieu tinh - ((hanh trang) or (anh tang)) luan tuong cong ((tan toan) OR (van toan)) tap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho lieu tinh - ((hanh trang) OR (anh tang)) luan tuong cong ((tan toan) OR (van toan)) tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho lieu tinh - ((hanh trang) or (anh tang)) luan tuong cong ((tan toan) OR (van toan)) tap*".
