If we don't care about scoring then for certain candidate matches we can be certain, that if they are a candidate match,
then they will always match. So verifying these queries with the MemoryIndex can be skipped.
Currently we don't throw an error when there is more than one query clause
specified in a must/must_not/should/filter object of the bool query without
using array notation, e.g.:
{ "bool" : { "must" : { "match" : { ... }, "match": { ... }}}}
In these cases, only the first query will be parsed and further behaviour is
unspecified, possibly leading to silently ignoring the rest of the query.
Instead we should throw a ParsingException if we don't encounter an END_OBJECT
token after having parsed the query clause.
This moves the "Performance Considerations for Elasticsearch Indexing" blog post
to the reference guide and adds similar recommendations for tuning disk usage
and search speed.

In GCS Repository plugin we defined a `service_account` setting which is defined as `Property.Filtered`.
It's not needed as it's only a path to a file.
Closes#18946
Global cluster blocks were not checked if an empty set of indices were passed as argument to the block checking method. This would lead to issues where some operations are already executed on a cluster before it has recovered its cluster state.
This commit updates the SHA for the JNA dependency. The JNA dependency
was upgraded from version 4.1.0 to version 4.2.2 in commit
7f101743629451c0ce115aa81e0577cee947d6f4 but the SHA was not updated.
This commit upgrades JNA from version 4.1.0 to 4.2.2. Additionally, this
dependency is now non-optional as JNA is dual-licensed with Apache
License 2.0 since JNA 4.0.0.

Some Rest tests use the Sun HTTP server which has lingering threads after shutdown. Similar to ESTestCase, this adds an
option to wait 5 seconds for these threads to terminate.
This is the same as what Lucene does for its analysis factories, and we hawe
tests that make sure that the elasticsearch factories are in sync with
Lucene's. This is a first step to move forward on #9978 and #18064.
I suspect recent failures are due to the fact that the cache disables itself
when there is contention. This runs assertions in an assertBusy block since
they should eventually succeed.
This commit moves template support out of the Search API to its own dedicated Search Template API in the lang-mustache module. It provides a new SearchTemplateAction that can be used to render templates before it gets delegated to the usual Search API. The current REST endpoint are identical, but the Render Search Template endpoint now uses the same Search Template API with a new "simulate" option. When this option is enabled, the Search Template API only renders template and returns immediatly, without executing the search.
Closes#17906
There are secondary issues with async shard fetch going out to nodes before they have a cluster state published to them that need to be solved first. For example:
- async fetch uses transport node action that resolves nodes based on the cluster state (but it's not yet exposed by ClusterService since we inline the reroute)
- after disruption nodes will respond with an allocated shard (they didn't clean up their shards yet) which throws of decisions master side.
- nodes deed the index meta data in question but they may not have if they didn't recieve the latest CS
We aren't able to actually create an index with _timestamp enabled
to test the migration, or, at least, we won't be able to after #18980
is re-merged. But the docs are still ok.

:client ---------> :client:rest
:client-sniffer -> :client:sniffer
:client-test ----> :client:test
This lines the client up with how we do things like modules and
plugins.
The lucene-test dependency caused issues with IDEs as they would always load the lucene 5 jar although they shouldn't have, which caused jarhell in es core tests.
If we depend directly on randomized runner we don't have this problem. It is luckily still compatible with java 1.7. This requires though adding a thin module that includes the base test class which can be shared between client and client-sniffer.
If a plugin declares `onModule(SomethingThatIsntAModule)` then refuse
to start. Before this commit we just logged a warning that flies by in
the console and is easy to miss. You can't miss refusing to start!
This commit removes duplicated methods for reading byte arrays in
StreamInput. One method would read a byte array by repeatedly calling
StreamInput#readByte in a loop, and the other would just call
StreamInput#readBytes. In this commit, we remove the former.
Relates #19023
`stored_fields` parameter will no longer try to retrieve fields from the _source but will only return stored fields.
`fields` will throw an exception if the user uses it.
Add `docvalue_fields` as an adjunct to `fielddata_fields` which is deprecated. `docvalue_fields` will try to load the value from the docvalue and fallback to fielddata cache if docvalues are not enabled on that field.
Closes#18943
