Perhaps you should try some spelling variations:
manpower resources » power resources, power resource, manager resource
manager resources » manager resource, managed resources, manage resources
22 costs » 2.2 costs, 2 costs, 22 cost
12 costs » 12 cost, 2 costs, 12 codes
21 costs » 21 cost, 1 costs, 11 costs
_ costs » _ cost

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %((manpower resources) OR (manager resources)) %((((((22 costs) OR (12 costs))) OR (_ costs))) OR (21 costs))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((manpower resources) or (manager resources)) %((((((22 costs) OR (12 costs))) or (_ costs))) or (21 costs))%22".
• Adding a wildcard symbol may retrieve word variants: %((manpower resources) or (manager resources)) %((((((22 costs) OR (12 costs))) or (_ costs))) or (21 costs))%22*.
