Here is a clever way to search for EU bilingual documents.
1) Go to Google Advanced Search (http://www.google.es/
2) In “all these words” type bilingual
3) Enter in “this exact word or phrase” the word or phrase you are looking for
4) Under “Narrow results by”
a) Select the language (for example, “Spanish”)
b) In “site or domain” type .eu
