I think this function *should* do what you want:

====================

(defun pk-ebib-search-for-field-value (field search-string)
  "Search the Ebib databases for SEARCH-STRING.
Return the entry key of the first entry found to contain SEARCH-STRING in FIELD."
  (catch 'found
    (mapc #'(lambda (db)
              (maphash #'(lambda (key val)
                           (let ((field-value (gethash field val)))
                             (if (and field-value
                                      (string-match search-string field-value))
                                 (throw 'found key))))
                       (edb-database db)))
          ebib-databases)))

====================

Note that the first argument, FIELD, should be a symbol, so in your
case, you want to call the function in this way:

(pk-ebib-search-for-field-value 'file "Some_File.pdf")

Let me know if you run into any problems.
