Daniel Aschauer commented on LUCENE-6012:
-----------------------------------------

Thanks, Michael!
Yes, i recognized that it is a limitation, but i am not aware why it is 
restricted to a SHORT value. Suggestions in my case are based on the field of 
the main content, so yes eventually there is a lot of text coming in. Is the 
limitation of 32767 the length of the text (measured in bytes) in the field, or 
what is exactly what I would have to shorten in my case?
