This commit adds the boolean similarity scoring from Lucene to
Elasticsearch. The boolean similarity provides a means to specify that
a field should not be scored with typical full-text ranking algorithms,
but rather just whether the query terms match the document or not.
Boolean similarity scores a query term equal to its query boost only.
Boolean similarity is available as a default similarity option and thus
a field can be specified to have boolean similarity by declaring in its
mapping:
"similarity": "boolean"

This commit addresses an issue with the docs for plugin install via a
proxy on Windows where the HTTP proxy options were incorrectly
specified.

The OpenJDK project provides early-access builds of upcoming
releases. These early-access builds are not suitable for
production. These builds sometimes end up on systems due to aggressive
packaging (e.g., Ubuntu). This commit adds a bootstrap check to ensure
these early-access builds are not being used in production.

This is especially useful when we rewrite the query because the result of the rewrite can be very different on different shards. See #18254 for example.
* Add support for fragment_length in the unified highlighter
This commit introduce a new break iterator (a BoundedBreakIterator) designed for the unified highlighter
that is able to limit the size of fragments produced by generic break iterator like `sentence`.
The `unified` highlighter now supports `boundary_scanner` which can `words` or `sentence`.
The `sentence` mode will use the bounded break iterator in order to limit the size of the sentence to `fragment_length`.
When sentences bigger than `fragment_length` are produced, this mode will break the sentence at the next word boundary **after**
`fragment_length` is reached.
The reindex API is mature now, and we will work to maintain backwards
compatibility in accordance with our backwards compatibility
policy. This commit unmarks the reindex API as experimental.

In SI units, "kilobyte" or "kB" would mean 1000 bytes, whereas "KiB" is
used for 1024. Add a note in `api-conventions.asciidoc` to clarify the
meaning in Elasticsearch.
In this repository, `Settings.builder` is used everywhere although it does exactly same as `Settings.settingsBuilder`. With the reference of the commit 42526ac28e , I think mistakenly this `Settings.settingsBuilder` remains in.
This commit adds a system property that enables end-users to explicitly
enforce the bootstrap checks, independently of the binding of the
transport protocol. This can be useful for single-node production
systems that do not bind the transport protocol (and thus the bootstrap
checks would not be enforced).

This commit adds a note to the resiliency status page regarding the fact
that replicas can fall out of sync with the primary shard after primary
promotion occurs due to a failing primary shard.

This commit adds the size of the cluster state to the response for the
get cluster state API call (GET /_cluster/state). The size that is
returned is the size of the full cluster state in bytes when compressed.
This is the same size of the full cluster state when serialized to
transmit over the network. Specifying the ?human flag displays the
compressed size in a more human friendly manner. Note that even if the
cluster state request filters items from the cluster state (so a subset
of the cluster state is returned), the size that is returned is the
compressed size of the entire cluster state.
Closes#3415
Throw error when skip or do sections are malformed, such as they don't start with the proper token (START_OBJECT). That signals bad indentation, which would be ignored otherwise. Thanks (or due to) our pull parsing code, we were still able to properly parse the sections, yet other runners weren't able to.
