Hi Edwin,
If it is one time thing you can use regex to filter out results that are not 
long enough. Something like: subject:/.{255,}.*/.
Of course, this means subject is not tokenized.

It would be probably best if you index subject length as separate field and 
include it in query as subject_length:[255 TO *].

HTH,
Emir
