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