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