Perhaps you should try some spelling variations:
"decentralized prozessmanagement _" » "decentralized management _"
"decentralized processing management" » "centralized processing management", "decentralized process management", "decentralised process management"
"decentralized biomass management" » "decentralized biowaste management", "decentralized cross management", "decentralized mas management", "decentralized process management", "decentralized prozess management", "decentralized loss management"
"centralized wireless management" » "centralized awareness management", "centralized witness management", "centralized wilderness management"

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: (((((("decentralized biomass management") OR ("decentralized prozessmanagement _"))) OR ("decentralized processing management"))) OR ((("centralized wireless management") OR ("centric wireless management")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"decentralized biomass management\") or (\"decentralized prozessmanagement _\"))) or (\"decentralized processing management\"))) or (((\"centralized wireless management\") OR (\"centric wireless management\"))))".
• Removing quotes may allow a broader search: (((((( decentralized biomass management ) or ( decentralized prozessmanagement _ ))) or ( decentralized processing management ))) or ((( centralized wireless management ) OR ( centric wireless management )))).
• Adding a wildcard symbol may retrieve word variants: (((((("decentralized biomass management") or ("decentralized prozessmanagement _"))) or ("decentralized processing management"))) or ((("centralized wireless management") OR ("centric wireless management"))))*.
