• If you are trying to use Boolean operators, they must be ALL CAPS: ((thuat sach) OR (thuat san)) ky nang xa hoi. lieu ((va cam) OR (va cac)) duc manh hang vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thuat sach) or (thuat san)) ky nang xa hoi. lieu ((va cam) OR (va cac)) duc manh hang vi cua te".
• Adding a wildcard symbol may retrieve word variants: ((thuat sach) or (thuat san)) ky nang xa hoi. lieu ((va cam) OR (va cac)) duc manh hang vi cua te*.
