• If you are trying to use Boolean operators, they must be ALL CAPS: tu van ky ((((nang xa) OR (nang x))) OR (tang ma)) hoi. hieu va cac xuc va danh co cua su.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu van ky ((((nang xa) OR (nang x))) or (tang ma)) hoi. hieu va cac xuc va danh co cua su".
• Adding a wildcard symbol may retrieve word variants: tu van ky ((((nang xa) OR (nang x))) or (tang ma)) hoi. hieu va cac xuc va danh co cua su*.
