• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ky sang lai hoa. ((hieu sau) OR (tieu su)) chat xuc va hanh ((thai cua) OR (than cua)) te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky sang lai hoa. ((hieu sau) OR (tieu su)) chat xuc va hanh ((thai cua) or (than cua)) te~".
• Adding a wildcard symbol may retrieve word variants: tu san ky sang lai hoa. ((hieu sau) OR (tieu su)) chat xuc va hanh ((thai cua) or (than cua)) te*.
