• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sai) OR (tu bai)) ky nang x hoi. hieu van cam duc va ((hanh va) OR (thanh tai)) sua chu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sai) OR (tu bai)) ky nang x hoi. hieu van cam duc va ((hanh va) or (thanh tai)) sua chu".
• Adding a wildcard symbol may retrieve word variants: ((tu sai) OR (tu bai)) ky nang x hoi. hieu van cam duc va ((hanh va) or (thanh tai)) sua chu*.
