We lost the `logger.transport.name` line in #65169 and I incorrectly
extrapolated from what was left and mangled it further in #66318. This
commit fixes things.
Today the docs use `logger.org.elasticsearch.transport: TRACE` as the
example for adjusting the logger config. This is a dangerous thing to
suggest since that's one of the most verbose loggers we have. An
accidental copy-and-paste of this example into a busy cluster can
cause damage.
This commit suggests `logger.org.elasticsearch.discovery: DEBUG`
instead, which is much more benign.
It also corrects the order of the levels and notes that `DEBUG` and
`TRACE` are only for expert use.
The option to use templates already defined in the cluster is not explicitly stated in the docs.
This PR adds and example to the `rank_eval` documentation.
Today we document the use of `_[networkInterface]_` to specify the
addresses of a network interface but do not spell out which parts of
this syntax should be taken literally and which are part of the
placeholder for the interface name.
This commit clarifies the docs.
NB this is a backport of just the docs changes from #66013.
Closes#65978.
Today we document the settings used to control rebalancing and
disk-based shard allocation but there isn't really any discussion around
what these processes do so it's hard to know what, if any, adjustments
to make.
This commit adds some words to help folk understand this area better.
In case the local agg sorter queue gets full and no limit has been provided,
the local sorter will now erroneously call the failure callback for every
single row in the original rowset that's left over the local queue limit
(instead for just the first one). The failure response is dispatched in any
case, so this is relatively harmless. The sorter continues iterating on the
original response fetching subsequent pages. In case of correct Elasticsearch
behaviour, this is also harmless, it'll just trigger a number of internal
exceptions. However, in case of a pagination defect in Elasticsearch (like
GH#65685, where the same search_after is returned), this will result in an
effective spin loop, potentially rendering eventually the node unresponsive.
This PR simply breaks both the inner loop iterating over the current unsorted
rowset, as well as the outer one, iterating over the left pages.
It also fixes an outdated documentation limitation.

The `lucene_version_path` variable is used in urls pointing to the Lucene docs.
They use underscore separators for the major and minor versions there.
Correcting this since this has been lost in the latest update on the 7.x branch.
