we have day wise elasticsearch indices they do contain millions of documents and we are maintaining one rollup index of them as well, so the problem is
1. when I used aggregation on one field on rollup index, I got some buckets in response but the problem is some intermediate buckets were missing.
2. as soon as I increased the size of the aggregation I got those missing buckets as well in the right order.
3. I tried both the solutions given in [this link](https://discuss.elastic.co/t/accuracy-issue-of-aggregation-results/19823), but not a single one worked for me.
4. any help would be appreciated. Thanks in advance!
- Is **shard\_size** parameter supported in **\_rollup\_search**? coz I tried some large values with it(eg. "shard\_size":50000) but didn't see any change in the result, only got missing buckets when increased the value of "size" parameter in aggs (eg. from "size":10 to "size":11)
