• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty xang cau hoi. hieu ve ((cam lo) or (cam ly)) ((va anh) OR (van anh)) va cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty xang cau hoi. hieu ve ((cam lo) OR (cam ly)) ((va anh) OR (van anh)) va cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty xang cau hoi. hieu ve ((cam lo) or (cam ly)) ((va anh) OR (van anh)) va cua triet".
• Adding a wildcard symbol may retrieve word variants: tu sach ty xang cau hoi. hieu ve ((cam lo) or (cam ly)) ((va anh) OR (van anh)) va cua triet*.
