GraphQueries are now generated as simple clauses in BooleanQuery. So for instance a multi terms synonym will generate
a GraphQuery but only for the side paths, the other part of the query will not be impacted. This means that we cannot apply
`minimum_should_match` or `cutoff_frequency` on GraphQuery anymore (only ES 5.3 does that because we generate all possible paths if a query has at least one multi terms synonym).
Starting in 5.4 multi terms synonym will now be treated as a single term when `minimum_should_match` is computed and will be ignored when `cutoff_frequency` is set.
Fixes#23102
Limits the length of `IndexRequest#toString` which also limits the size of the task description generated for `IndexRequest`s. If the document being written is larger than 2kb we skip logging the _source entirely. This is because truncating the source is tricky and it isn't worth it.
Index HEAD requests incorrectly return a content-length header of
0. This commit addresses this by removing the special handling for index
HEAD requests, and just relying on the general mechanism that exists for
handling HEAD requests in the REST layer.

Alias HEAD requests incorrectly return a content-length header of
0. This commit addresses this by removing the special handling for alias
HEAD requests, and just relying on the general mechanism that exists for

This commit adds methods to the BulkProcessor that accept bytes and a XContentType to avoid content type detection. The
methods that do not accept XContentType with bytes have been deprecated by this commit.

This commit is just a code cleanup of RestGetAliasesAction.java. For
example, we remove an unnecessary class, simplify a convenience method,
and simplify some code flow.

This pull request reuses the typed_keys parameter added in #22965, but this time it applies it to suggesters. When set to true, the suggester names in the search response will be prefixed with a prefix that reflects their type.
It looked like it was telling you to add both `// TEST[continued]`
and `// TESTRESPONSE` to the same snippet which doesn't do anything.
Instead it was trying to say that you can have many snippets included
into the same test by doing:
```
request1
```
// CONSOLE
```
response1
```
// TESTRESPONSE
``
request2
```
// CONSOLE
// TEST[continued]
```
response2
```
// TESTRESPONSE
EvillPeerRecoveryIT checks scenario where recovery is happening while there are on going indexing operation that already have been assigned a seq# . This is fairly hard to achieve and the test goes through a couple of hoops via the plugin infra to achieve that. This PR extends the unit tests infra to allow for those hoops to happen in unit tests. This allows the test to be moved to RecoveryDuringReplicationTests

This changes removes the SearchResponseListener that was used by the ExpandCollapseSearchResponseListener to expand collapsed hits.
The removal of SearchResponseListener is not a breaking change because it was never released.
This change also replace the blocking call in ExpandCollapseSearchResponseListener by a single asynchronous multi search request. The parallelism of the expand request can be set via CollapseBuilder#max_concurrent_group_searches
Closes#23048
Now that we use bulk for single item indexing, this is often the case. Having an indicator of the id of the indexed document helps debugging.
It now looks like this `BulkShardRequest to [[test][0]] containing [index {[test][type][AVojzy9ZxfWASZ-ysmN7], source[{"auto":true}]}]`
Empty response bodies should only be sent for HEAD requests, otherwise we should always send back info about the exception that was thrown. Removed some manual exception handling in the REST action that should be rather bubbled up and handled by our rest action infra like every other rest action does.
Netty 4.1.8 wraps connect and accept operations in doPrivileged blocks.
This means that we not need to give permissions to the entire transport
module. Additionally this commit deletes the privileged socket channel
and privileged server socket chanel.
This pull request adds a new parameter to the REST Search API named `typed_keys`. When set to true, the aggregation names in the search response will be prefixed with a prefix that reflects the internal type of the aggregation.
Here is a simple example:
```
GET /_search?typed_keys
{
"aggs": {
"tweets_per_user": {
"terms": {
"field": "user"
}
}
},
"size": 0
}
```
And the response:
```
{
"aggs": {
"sterms:tweets_per_user": {
...
}
}
}
```
This parameter is intended to make life easier for REST clients that could parse back the prefix and could detect the type of the aggregation to parse. It could also be implemented for suggesters.
Today we account for too many response with an `IllegalStateException` in
`AbstractSearchAsyncAction` while this is something that should never happen
we should rather assert that we are always have less or equal the number of
expected ops when waiting for responses.
This commit removes support for the `application/x-ldjson` Content-Type header as this was only used in the first draft
of the spec and had very little uptake. Additionally, the docs for bulk and msearch have been updated to specifically
call out ndjson and mention that the newline character may be preceded by a carriage return.
Finally, the bulk request handling of the carriage return has been improved to remove this character from the source.
Closes#23025
This is just a temporary fix until #23048 is fixed. FieldCollapsing
is executing blocking calls on a network thread which causes potential deadlocks
and trips assertions.

We have a bunch of interfaces that have only a single implementation
for 6 years now. These interfaces are pretty useless from a SW development
perspective and only add unnecessary abstractions. They also require
lots of casting in many places where we expect that there is only one
concrete implementation. This change removes the interfaces, makes
all of the classes final and removes the duplicate `foo` `getFoo` accessors
in favor of `getFoo` from these classes.
After the first cluster state from a new master is processed, NodeConnectionService guarantees we connect to the new master. This removes the need to explicitly connect to the master in the MasterFaultDetection code making it simpler and bypasses the assertion triggered due to the blocking operation on the cluster state thread.

Today we carry on all search results including aggs, suggest and profile results
until we have successfully fetched all hits for the search request. This can potentially
hold on to a large amount of memory if there are heavy aggregations involved. With
this change aggs and profiles are entirely consumed an released for GC before the fetch
phase is executing. This is a first step towards reducing results on-the-fly if the number
of non-empty response are large.
Elasticsearch v5.0.0 uses allocation IDs to safely allocate primary shards whereas prior versions of ES used a version-based mode instead. Elasticsearch v5 still has support for version-based primary shard allocation as it needs to be able to load 2.x shards. ES v6 can drop the legacy support.
