• If you are trying to use Boolean operators, they must be ALL CAPS: vu ban ((((ky sang) OR (ky dang))) OR (ky tang)) xa hoi. hieu van cam tuc va nang via cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ban ((((ky sang) OR (ky dang))) or (ky tang)) xa hoi. hieu van cam tuc va nang via cua tre".
