• Performing a fuzzy search may retrieve terms with similar spellings: thuoc sach ty xang ((x hoi) OR (xa hoi)). ((hieu ve) or (lieu va)) lam duc ban danh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach ty xang ((x hoi) OR (xa hoi)). ((hieu ve) OR (lieu va)) lam duc ban danh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach ty xang ((x hoi) OR (xa hoi)). ((hieu ve) or (lieu va)) lam duc ban danh vi cua triet".
