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