• If you are trying to use Boolean operators, they must be ALL CAPS: ((((te sac) OR (te cac))) OR (te san)) ky lang xa hoi. hieu van nam xuc va dinh va cau tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((te sac) OR (te cac))) or (te san)) ky lang xa hoi. hieu van nam xuc va dinh va cau tre".
• Adding a wildcard symbol may retrieve word variants: ((((te sac) OR (te cac))) or (te san)) ky lang xa hoi. hieu van nam xuc va dinh va cau tre*.
