• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu san) OR (phu san)) ky nang x hoi. hieu ((ve cam) OR (ve cac)) duc van hanh dai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu san) OR (phu san)) ky nang x hoi. hieu ((ve cam) or (ve cac)) duc van hanh dai cua te".
• Adding a wildcard symbol may retrieve word variants: ((thu san) OR (phu san)) ky nang x hoi. hieu ((ve cam) or (ve cac)) duc van hanh dai cua te*.
