integration theory » integration through, information theory, innovation theory
dateu integration » data integration, deep integration, die integration
supply dateu » supply water, supply rates, supply data
supply eu » supply a, supply 3, supply 4

• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((supply eu) OR (supply _)) integration efforts. ) OR ( supply dateu integration theory. ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((supply eu) OR (supply _)) integration efforts. ) or ( supply dateu integration theory. ))*".
