Perhaps you should try some spelling variations:
"venezuela, republica bolivariana de" » "venezuela, republic bolivia de", "venezuela, republica bolivarian _"
"venezuela, public bulgaria _" » "venezuela, republic bulgaria _", "venezuela, republics bulgaria _", "venezuela, muslims bulgaria _"
"venezuela, policy bulgaria _" » "venezuela, policies bulgaria _", "venezuela, politics bulgaria _", "venezuela, polish bulgarian _"

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: (("venezuela, republica bolivariana de") OR ((("venezuela, public bulgaria _") OR ("venezuela, policy bulgaria _")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"venezuela, republica bolivariana de\") or (((\"venezuela, public bulgaria _\") OR (\"venezuela, policy bulgaria _\"))))".
• Removing quotes may allow a broader search: (( venezuela, republica bolivariana de ) or ((( venezuela, public bulgaria _ ) OR ( venezuela, policy bulgaria _ )))).
• Adding a wildcard symbol may retrieve word variants: (("venezuela, republica bolivariana de") or ((("venezuela, public bulgaria _") OR ("venezuela, policy bulgaria _"))))*.
