Essentially, just write in and say “Please accelerate the search and examination of my application.” Preferably it can be done by sending in this form:
http://www.european-patent-office.org/epo/formul/epc/1005_e.pdf

To be fair, you’ll still get the quickest results if you cooperate with the Examiner to get his/her goodwill. Answer objections quickly, and put your application in good order before examination. (E.g. don’t file US-style multiple independent claims that don’t meet European formal requirements and that will provoke an objection separate from any patentability issue.)
