• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ky lang xa hoi. hieu van hac tri van doanh ((((cho cua) OR (chi cua))) OR (cong cua)) te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ky lang xa hoi. hieu van hac tri van doanh ((((cho cua) OR (chi cua))) or (cong cua)) te~".
• Adding a wildcard symbol may retrieve word variants: toc sach ky lang xa hoi. hieu van hac tri van doanh ((((cho cua) OR (chi cua))) or (cong cua)) te*.
