• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky nang x hoi. hieu ((ca nam) OR (cai nam)) ((thu va) or (thue va)) hanh vai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky nang x hoi. hieu ((ca nam) OR (cai nam)) ((thu va) OR (thue va)) hanh vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky nang x hoi. hieu ((ca nam) OR (cai nam)) ((thu va) or (thue va)) hanh vai cua triet".
