Perhaps you should try some spelling variations:
integration model » integration models, integrative model, interaction model
de integration » die integration, re integration, une integration
support eat » support each, support a, support can
support act » support a, support add, support action
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 model. ) OR ( ((support eat) OR (support act)) innovation through. ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( support de integration model. ) or ( ((support eat) OR (support act)) innovation through. ))~".
• Adding a wildcard symbol may retrieve word variants: (( support de integration model. ) or ( ((support eat) OR (support act)) innovation through. ))*.
