Perhaps you should try some spelling variations:
integration efforts » international efforts, conservation efforts
eu integration » deep integration, die integration, data integration
sound banking » unsound banking, south banking, sound tracking
round banking » round walking, unsound banking, land banking
support eu » support _, support a, support 4

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( support eu integration efforts. ) or ( supply ((sound banking) OR (round banking)) series. ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( support eu integration efforts. ) OR ( supply ((sound banking) OR (round banking)) series. ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( support eu integration efforts. ) or ( supply ((sound banking) OR (round banking)) series. ))*".
