Perhaps you should try some spelling variations:
manpower resources » power resources, manager resources, power resource
managed resources » unmanaged resources, managing resources, management resources
manager resource » managing resource, management resource, unmanaged resources
manage resources » unmanaged resources, language resources, managing resources
manage resource » language resource, managing resource, package resource
22 costs » 2.2 costs, 12 costs, 22 cost
21 costs » 21 cost, 1 costs, 11 costs
2 costs » 2 cost, 4 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 resource) OR (((((manage resources) OR (manage resource))) OR (managed resources)))))) %((((22 costs) OR (((2 costs) OR (_ costs))))) OR (21 costs))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((manpower resources) or (((manager resource) or (((((manage resources) OR (manage resource))) or (managed resources)))))) %((((22 costs) or (((2 costs) or (_ costs))))) or (21 costs))%22".
• Adding a wildcard symbol may retrieve word variants: %((manpower resources) or (((manager resource) or (((((manage resources) OR (manage resource))) or (managed resources)))))) %((((22 costs) or (((2 costs) or (_ costs))))) or (21 costs))%22*.
