Hi,
As terms aggregation will collect top size terms on each shard, so the
final result may not accuracy if the shard size is not big enough.
so, in order to promote the accuracy of terms aggregation, we may need
to calculate a weighted value by size. if there are more
documents on the shard, the terms collected on this shard will be
greater. This means that we do not collect same size terms on each
shard.
so, we want to develop a customized plug-in which has the same manner
with terms aggregation and different way of collecting terms on each shard.
The simple way is to inherit from terms aggregation, and override the
way of collecting terms on each shard, but this seems difficulty,
because some classes in terms aggregation can only be accessed in
package scope like the Bucket class.
we can also copy the whole source code of terms aggregation into our
customized plug-in, but I don't think this is a good way.
Is it a good way to inherit from terms aggregation in user customized
plug-in?
And Is there a good way to extend the terms aggregation?
Thanks,
ming
