Docs issue: search.max_buckets default value different in two pages for ES 7.10

[bernardobelchior]

Elasticsearch version (bin/elasticsearch --version): 7.10

Plugins installed: []

JVM version (java -version): N/A

OS version (uname -a if on a Unix-like system): N/A

Description of the problem including expected versus actual behavior:

Actual behavior: https://www.elastic.co/guide/en/elasticsearch/reference/7.10/search-aggregations-bucket.html says that default value for search.max_buckets is 65,535, but https://www.elastic.co/guide/en/elasticsearch/reference/7.10/search-settings.html#search-settings-max-buckets mentions 10,000.

Expected behavior: both pages should agree on the default value (either 65,535 or 10,000)

Steps to reproduce:

1. Go to https://www.elastic.co/guide/en/elasticsearch/reference/7.10/search-aggregations-bucket.html. You can read

The maximum number of buckets allowed in a single response is limited by a dynamic cluster setting named search.max_buckets. It defaults to 65,535, requests that try to return more than the limit will fail with an exception.

2. The search.max_buckets link links here, where you can read:

search.max_buckets
(Dynamic, integer) Maximum number of aggregation buckets allowed in a single response. Defaults to 10000.

These values are conflicting and seems to have been caused in 7.10 only. The 7.9 version of both pages say that the default is 65,535, as well as ElasticSearch 7.10 release announcement:

in 7.9 we increased the search.max_buckets limit to 65,535

Just wanted to bring attention to this, as it is a bit confusing.

Thanks for raising this @bernardobelchior. The correct default is 65,535.
