Jim Ferenczi 423291b6bc Change default similarity to BM25
The default similarity was set to `classic` which refers to TFIDF and has not been moved after the upgrade to Lucene 6.

Though moving to BM25 could have some downside for queries that relies on coordination factor (match_query, multi_match_query) ?

Nik Everett 6569d35094 Fail doc tests when any shard fails
ES only sends a non-200 response all shards fail but we should
fail the tests generated by docs if any of them fail.

Depending on the outcome of #18978 this might be a temporary
workaround.

Adrien Grand 93415d4506 Expose MMapDirectory.preLoad(). #18880
The MMapDirectory has a switch that allows the content of files to be loaded
into the filesystem cache upon opening. This commit exposes it with the new
`index.store.pre_load` setting.

Jason Tedor d09d89f8c5 Remove only node preference
This commit removes the search preference _only_node as the same
functionality can be obtained by using the search preference
_only_nodes. This commit also adds a test that ensures that _only_nodes
will continue to support specifying node IDs.

Jason Tedor 245def80f0 Add note that thread pool settings are node-level
This commit adds a note to the breaking changes docs that since commit
da74323141, thread pool settings are no
longer cluster-level settings and thus not dynamically updatable.

Nik Everett b665d8a187 Painless: Add flag support to regexes
Painless: Add support for //m
Painless: Add support for //s
Painless: Add support for //i
Painless: Add support for //u
Painless: Add support for //U
Painless: Add support for //l
  This means "literal" and is exposed for completeness sake with
  the java api.
Painless: Add support for //c
  c enables Java's CANON_EQ (canonical equivalence) flag which makes
  unicode characters that are canonically equal match. Java's javadoc
  gives "a\u030A" being equal to "\u00E5". That is that the "a" code
  point followed by the "combining ring above" code point is equal to
  the "a with combining ring above" code point.
Update docs and add multi-flag test
Whitelist most of the Pattern class.

Nik Everett 8d3ef742db Painless: =~ and ==~ operators
Adds support for the find operator (=~) and the match operator (==~)
to painless's regexes. Also whitelists most of the Matcher class and
documents regex support in painless.

The find operator (=~) returns a boolean that is the result of building
a matcher on the lhs with the Pattern on the RHS and calling `find` on
it. Use it like this:

```
if (ctx._source.last =~ /b/)
```

The match operator (==~) returns boolean like find but instead of calling
`find` on the Matcher it calls `matches`.

```
if (ctx._source.last ==~ /[^aeiou].*[aeiou]/)
```

Finally, if you want the actual matcher you do:

```
Matcher m = /[aeiou]/.matcher(ctx._source.last)
```

Adrien Grand 9ffb2ff6ba Expose half-floats. #18887
They have been implemented in https://issues.apache.org/jira/browse/LUCENE-7289.
Ranges are implemented so that the accuracy loss only occurs at index time,
which means that if you are searching for values between A and B, the query will
match exactly all documents whose value rounded to the closest half-float point
is between A and B.

Jason Tedor e96722d91c Add search preference to prefer multiple nodes
The search preference _prefer_node allows specifying a single node to
prefer when routing a request. This functionality can be enhanced by
permitting multiple nodes to be preferred. This commit replaces the
search preference _prefer_node with the search preference _prefer_nodes
which supplants the former by specifying a single node and otherwise
adds functionality.

Nik Everett e392e0b1df Create get task API that falls back to the .tasks index
This adds a get task API that supports GET /_tasks/${taskId} and
removes that responsibility from the list tasks API. The get task
API supports wait_for_complation just as the list tasks API does
but doesn't support any of the list task API's filters. In exchange,
it supports falling back to the .results index when the task isn't
running any more. Like any good GET API it 404s when it doesn't
find the task.

Then we change reindex, update-by-query, and delete-by-query to
persist the task result when wait_for_completion=false. The leads
to the neat behavior that, once you start a reindex with
wait_for_completion=false, you can fetch the result of the task by
using the get task API and see the result when it has finished.

Also rename the .results index to .tasks.

Martijn van Groningen 3b96055b23 msearch: Cap the number of searches the msearch api will concurrently execute
By default the number of searches msearch executes is capped by the number of
nodes multiplied with the default size of the search threadpool. This default can be
overwritten by using the newly added `max_concurrent_searches` parameter.

Before the msearch api would concurrently execute all searches concurrently. If many large
msearch requests would be executed this could lead to some searches being rejected
while other searches in the msearch request would succeed.

The goal of this change is to avoid this exhausting of the search TP.

Previously Elasticsearch used $DATA_DIR/$CLUSTER_NAME/nodes for the path

On startup, if the old folder structure is detected it will be used.
This behavior will be removed in Elasticsearch 6.0
