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