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