Perhaps you should try some spelling variations:
manpower resources » power resources, manager resources, power resource
managed resources » manager resource, managing resources, management resources
2.7 costs » 12.7 costs, 2.7 cosets, 2.7 cost
27 costs » 27 costas, 17 costs, 27 cost
23 costs » 2.3 costs, 3 costs, 13 costs
21 costs » 21 cost, 1 costs, 11 costs
2 costs » _ costs, 2 cost, 4 costs

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 (((unmanaged resources) OR (managed resources)))) %((((((((27 costs) OR (2.7 costs))) OR (23 costs))) OR (2 costs))) OR (21 costs))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((manpower resources) or (((unmanaged resources) or (managed resources)))) %((((((((27 costs) OR (2.7 costs))) or (23 costs))) or (2 costs))) or (21 costs))%22".
• Adding a wildcard symbol may retrieve word variants: %((manpower resources) or (((unmanaged resources) or (managed resources)))) %((((((((27 costs) OR (2.7 costs))) or (23 costs))) or (2 costs))) or (21 costs))%22*.
