• Performing a fuzzy search may retrieve terms with similar spellings: thuoc sach ky lang xa hoi. hieu ve cao ((suc va) OR (duc va)) ((nhan viec) or (nha viec)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach ky lang xa hoi. hieu ve cao ((suc va) OR (duc va)) ((nhan viec) OR (nha viec)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach ky lang xa hoi. hieu ve cao ((suc va) OR (duc va)) ((nhan viec) or (nha viec)) cua te".
