Perhaps you should try some spelling variations:
integration theories » integration theorems, integrationstheorie 2, integration theory
domain information » human information, chain information, can information
de integration » die integration, re integration, une integration
supply domain » supply main, supply chain, supply demand
support de » support _, support a, support 4

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: (( support de integration theories. ) OR ( supply domain information theory. ))~.
• Adding a wildcard symbol may retrieve word variants: (( support de integration theories. ) or ( supply domain information theory. ))*.
