There are 2 things that i want to achieve for performance reasons.
I want to disable sorting and scoring in the results, since my intent is to just
retrieve 1000 matches in the quickest fashion.
The catch is I have full text clauses in my query part, so I can't possibly use a filter.
I tried filter with match and it doesn't work.
Is constant_score the way to go here?
I have 5 shards, so if is there a way to tell elastic to just retrieve 200 from each
shard and put them together .... i.e. should I say size=200 or size=1000 ?
With sorting and relevancy, I would need to give size=1000, because elastic has to
do a global sort.. but if I don't care about order, what should I do?
