Hi All
we use the terms aggregation to get the top n authors, but the
aggregation may not return the top n authors.
As the elasticsearch guide said, the aggregated results are not always
accurate.
Indeed we can increase the shard size to get more accurate results, but
if the buckets returned by each shard are big enough, there will be a a
bottleneck in master node reducing the final result.
Is there a other way to improve the accuracy of terms aggregation?
Is there a good way to decrease the press of master node when executing
the reducing phase?
Thanks
