Add min_doc_count option to geo grid aggregations

[yutaka-nakano]

Would it be possible to add min_doc_count option to geohash grid aggregation and geotile grid aggrigation?
We use Elasticsearch and Kibana for geospatial data analysis. min_doc_count option would be very helpful for us to mask privacy information on dashboards with maps. It would also be helpful for excluding outliers.

We created a Pull Request for this feature. #50480 Could you check it?

Update (January 2023) min_doc_count should also be added to

• geohexgrid
• Exposed via vector tile search API

There have been requests in Kibana for filtering geo aggregation buckets

This seems easy enough, as long as we exclude support for min_doc_count=0.

Hi @yutaka-nakano, is this still open? I would like to fix this issue.

@timDINOS yes it is still open and I think nobody is actively working on that so please feel free to work on it.

Hello, @timothy-choi are you working on this issue? I am looking for my first issue to attempt my first contribution and If no one is working with this one I would love to give it a shot.

We discussed this issue internally and we decided we don't want to pursue this idea anymore. Similarly to https://github.com/elastic/elasticsearch/issues/54649, we think Bucket selectors are the correct solution to do this type of operation and therefore I am closing this issue.
