• If you are trying to use Boolean operators, they must be ALL CAPS: phu san ky nang xa hoi. hieu ve ((cac duc) OR (cac dac)) ((va hang) OR (va lang)) di cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "phu san ky nang xa hoi. hieu ve ((cac duc) or (cac dac)) ((va hang) OR (va lang)) di cua tu".
• Adding a wildcard symbol may retrieve word variants: phu san ky nang xa hoi. hieu ve ((cac duc) or (cac dac)) ((va hang) OR (va lang)) di cua tu*.
