• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sac ky nang xa hoi. hieu ((ve cham) OR (va cham)) cuc ban ((hanh dai) OR (hanh tai)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sac ky nang xa hoi. hieu ((ve cham) OR (va cham)) cuc ban ((hanh dai) or (hanh tai)) cua te".
• Adding a wildcard symbol may retrieve word variants: thuoc sac ky nang xa hoi. hieu ((ve cham) OR (va cham)) cuc ban ((hanh dai) or (hanh tai)) cua te*.
