• Performing a fuzzy search may retrieve terms with similar spellings: tu sach tru nang xa hoi. hieu van ((cau xuc) OR (cau truc)) ((van anh) or (ban hanh)) vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach tru nang xa hoi. hieu van ((cau xuc) OR (cau truc)) ((van anh) OR (ban hanh)) vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach tru nang xa hoi. hieu van ((cau xuc) OR (cau truc)) ((van anh) or (ban hanh)) vi cua triet".
