• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly tang ma hoi. hieu van ((((cam duc) OR (cam xuc))) OR (pham duc)) ban hanh ly cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly tang ma hoi. hieu van ((((cam duc) OR (cam xuc))) or (pham duc)) ban hanh ly cua te".
• Adding a wildcard symbol may retrieve word variants: tu sach ly tang ma hoi. hieu van ((((cam duc) OR (cam xuc))) or (pham duc)) ban hanh ly cua te*.
