Help 1.x to 5.x search_type=count and size=0

[Karl_Putland]

I have a large query that I just need aggregations on.

In 1.7 I used search_type=count and the query runs fine.
in 5.x That option is no longer available, so I try size=0 and the query... adapted from filtered to bool w/ filter context is trying to return 1.5GB of data and stalls.

(
  "query": {
    "bool": {
       "filter": {
         "should": [ ... big giant filter list ...]
      } 
    }
  },
  "aggs": {
    "SOME_AGGS": { ... }
  }
  "size": 0
}

size: 0 is the right replacement. It's equivalent to count I suspect your issue is inside the filter. Try to run it without the aggs part and see how many docs it returns and how many it should.
