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