One of our key features for debugging is the slow log - but when folks have very large _searches we can end up with cut off slow logs. Something chops them. I recall that we had something to do that but I can't find it at the moment. Maybe its some external tool doing the chopping

Anyway! Maybe we could make the slow logs shorter by not outputting default parameters when we toXContent the search's source. Or something. I dunno. I've just been frustrated lately when looking at slow logs from folks that are cut off and want to do something about it.
