Docs: rewrite description of `bool`'s `should`
Rewrites the description of the `bool` query's `should`
clauses so it is (hopefully) more clear what the defaults
for `minimum_should_match` are.
There is still an `[IMPORTANT]` section about `minimum_should_match`
in a filter context. I think it is worth keeping because it is, well,
important.
Closes#23831
This commit adds a link to the minimum master nodes section of the
important settings docs from the Zen discovery docs to clarify the
meaning and importance of setting minimum master nodes to a quorum of
master-eligible nodes.

Workday recently open-sourced our internal Scala wrapper for the Elasticsearch REST API. We plan to continue maintaining the library and use it in our products. Thought it would be a good idea to link it here in case anyone else is interested in using it!
The `count` value in the stats aggregation represents a simple doc count
that doesn't require a formatted version. We didn't render an "as_string"
version for count in the rest response, so the method should also be
removed in favour of just using String.valueOf(getCount()) if a string
version of the count is needed.
Closes#24287
I just spent ages debugging a script I wrote after following the documentation. It was not clear to me that _index is not defined when using painless; if it was mentioned on this page I would have saved myself a lot of time.
For the Windows service, JAVA_HOME should be set to the path to the
JDK. We should make this clear in the docs to help users avoid
frustrating startup problems.

Add option "enable_position_increments" with default value true.
If option is set to false, indexed value is the number of tokens
(not position increments count)
This commit rewords the note on whitespace in Log4j settings to not
refer to only of the examples on the page, but instead be clear that the
note applies to all the examples on the page.
A confusing thing that can happen when configuring Log4j is that
extraneous whitespace throws off its configuration parsing yet the error
messages that arise give no indication that this is the problem. This
commit adds a note to the docs.

This commit removes the deprecated cloud.aws.* settings. It also removes
backcompat for specifying `discovery.type: ec2`, and unused aws signer
code which was removed in a previous PR.
This change adds an index setting to define how the documents should be sorted inside each Segment.
It allows any numeric, date, boolean or keyword field inside a mapping to be used to sort the index on disk.
It is not allowed to use a `nested` fields inside an index that defines an index sorting since `nested` fields relies on the original sort of the index.
This change does not add early termination capabilities in the search layer. This will be added in a follow up.

Elasticsearch runs as user elasticsearch with uid:gid 1000:1000 inside
the Docker container. Clarify that bind mounted local directories need
to be accessible by this user.

This change simplifies how the rest test runner finds test files and
removes all leniency. Previously multiple prefixes and suffixes would
be tried, and tests could exist inside or outside of the classpath,
although outside of the classpath never quite worked. Now only classpath
tests are supported, and only one resource prefix is supported,
`/rest-api-spec/tests`.
closes#20240
We want to upgrade to Lucene 7 ahead of time in order to be able to check whether it causes any trouble to Elasticsearch before Lucene 7.0 gets released. From a user perspective, the main benefit of this upgrade is the enhanced support for sparse fields, whose resource consumption is now function of the number of docs that have a value rather than the total number of docs in the index.
Some notes about the change:
- it includes the deprecation of the `disable_coord` parameter of the `bool` and `common_terms` queries: Lucene has removed support for coord factors
- it includes the deprecation of the `index.similarity.base` expert setting, since it was only useful to configure coords and query norms, which have both been removed
- two tests have been marked with `@AwaitsFix` because of #23966, which we intend to address after the merge
The docs don't clearly explain that the deleted doc count also comes from lucene.
IMHO, it is worth highlighting this information separately, as a Note.
Apart from that, there should be an official recommended alternative as well.
Today Elasticsearch allows default settings to be used only if the
actual setting is not set. These settings are trappy, and the complexity
invites bugs. This commit removes support for default settings with the
exception of default.path.data, default.path.conf, and default.path.logs
which are maintainted to support packaging. A follow-up will remove
support for these as well.

Drops any mention of non-sandboxed scripting languages other than a
brief "we don't support them and we shouldn't because A and B"
statement.
