would the following work for you?

//element(*, nt:file)[jcr:contains(jcr:content, 'Dokument')]

it assumes that your files have an nt:resource child node named jcr:content.

remarks:
- element(*, nt:file) also returns node with a subtype of nt:file
- jcr:contains() is more efficient than jcr:like for longer strings and you
   actually want to do a fulltext search
