• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ky nang ro hai. ((hieu va) OR (hieu qua)) cam xuc va tinh ((di cua) OR (dai cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky nang ro hai. ((hieu va) or (hieu qua)) cam xuc va tinh ((di cua) OR (dai cua)) te".
