Perhaps you should try some spelling variations:
manpower resources » power resources, manager resources, power resource
3.2 costs » 3.2 cost, 4.2 costs, 5.2 costs
2.2 costs » 12.2 costs, 2.2 cost, 2.2 costa
2f costs » 23 costs, 27 costs, 28 costs
26 costs » 2.6 costs, 26 cosets, 6 costs
22 costs » 12 costs, 12.2 costs, 4.2 costs
21 costs » 21 cost, 1 costs, 11 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 %((((((2f costs) OR (26 costs))) OR (((((((22 costs) OR (3.2 costs))) OR (22 cost))) OR (2.2 costs))))) OR (21 costs))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%manpower resources %((((((2f costs) OR (26 costs))) or (((((((22 costs) or (3.2 costs))) or (22 cost))) or (2.2 costs))))) or (21 costs))%22".
• Adding a wildcard symbol may retrieve word variants: %manpower resources %((((((2f costs) OR (26 costs))) or (((((((22 costs) or (3.2 costs))) or (22 cost))) or (2.2 costs))))) or (21 costs))%22*.
