The search_after parameter provides a way to efficiently paginate from one page to the next. This parameter accepts an array of sort values, those values are then used by the searcher to sort the top hits from the first document that is greater to the sort values.
This parameter must be used in conjunction with the sort parameter, it must contain exactly the same number of values than the number of fields to sort on.
NOTE: A field with one unique value per document should be used as the last element of the sort specification. Otherwise the sort order for documents that have the same sort values would be undefined. The recommended way is to use the field `_uuid` which is certain to contain one unique value for each document.
Fixes#8192
* Added percolator field mapper that extracts the query terms and indexes these terms with the percolator query.
* At percolate time these extracted terms are used to query percolator queries that are like to be evaluated. This can significantly cut down the time it takes to percolate. Whereas before all percolator queries were evaluated if they matches with the document being percolated.
* Changes made to percolator queries are no longer immediately visible, a refresh needs to happen before the changes are visible.
* By default the percolate api only returns upto 10 matches instead of returning all matching percolator queries.
* Made percolate more modular, so that it is easier to add unit tests.
* Added unit tests for the percolator.
Closes#12664Closes#13646
Provides a new flag which can be enabled on a per-request basis.
When `"profile": true` is set, the search request will execute in a
mode that collects detailed timing information for query components.
```
GET /test/test/_search
{
"profile": true,
"query": {
"match": {
"foo": "bar"
}
}
}
```
Closes#14889

Split collector serialization from timing, use writeable instead of streamable
Previously, the collector timing was done in the same class that was serialized, which required
leaving the collector null when serializing. Besides being a bit gross, this made it difficult to
change the class to Writeable.
This splits up the timing (InternalProfileCollector + ProfileCollector) and the serialization of
the times (CollectorResult). CollectorResult is writeable, and also acts as the public interface.

Merge duplicate rewrites into one entry
By using the Query as the key in a map, we can easily merge rewrites together. This means
the preProcess(), assertion and main query rewrites all get merged together. Downside is that
rewrites of the same Query (hashcode) but in different places get lumped together. I think the
simplicity of the solution is better than the slight loss in output fidelity.

nocommit - profiling never enabled because setProfile() on ContextIndexSearcher never called
Previously, it was enabled by using DefaultSearchContext as a third-party "proxy", but since
the refactor to make it unit testable, setProfile() needs to be called explicitly. Unfortunately,
this is not possible because SearchService only has access to an IndexSearcher. And it is not
cast'able to a DefaultIndexSearcher.

Move rewrites to their own section, remove reconciliation
Big commit because the structural change affected a lot of the wrapping code. Major changes:
- Rewrites are now in their own section in the response
- Reconciliation is gone...we don't attempt to roll the rewrites into the query tree structure
- InternalProfileShardResults (plural) simply holds a Map<String, InternalProfileShardResult> and
helps to serialize / ToXContent
- InternalProfileShardResult (singular) is now the holder for all shard-level profiling details. Currently
this includes query, collectors and rewrite. In the future it would hold suggest, aggs, etc
- When the user requests the profiled results, they get back a Map<String, ProfileShardResult>
instead of doing silly helper methods to convert to maps, etc
- Shard details are baked into a string instead of serializing the object

Fix multi-stage rewrites to recursively find most appropriate descendant rewrite
Previously, we chose the first rewrite that matched. But in situations where a query may
rewrite several times, this won't build the tree correctly. Instead we need to recurse
down all the rewrites until we find the most appropriate "leaf" rewrite
The implementation of this is kinda gross: we recursively call getRewrittenParentToken(),
which does a linear scan over the rewriteMap and tries to find rewrites with a larger token
value (since we know child tokens are always larger). Can almost certainly find a better
way to do this...

Add profiling of two-phase iterators.
This is useful for eg. phrase queries or script filters, since they are
typically consumed through their two-phase iterator instead of the scorer.

Some more improvements.
I changed profiling to disable bulk scoring, since it makes it impossible to
know where time is spent. Also I removed profiling of operations that are
always fast (eg. normalization) and added nextDoc/advance.

The completion suggester provides auto-complete/search-as-you-type functionality.
This is a navigational feature to guide users to relevant results as they are typing, improving search precision.
It is not meant for spell correction or did-you-mean functionality like the term or phrase suggesters.
The completions are indexed as a weighted FST (finite state transducer) to provide fast Top N prefix-based
searches suitable for serving relevant results as a user types.
closes#10746
The only way to refer to the plain highlighter is now `plain`, the only way to refer to the fast vector highlighter is `fvh` and the only way to refer to the postings highlighter is `postings`. The name variants like `highlighter`, `postings-highlighter` and `fast-vector-highlighter` have been removed.
we are relying on terminate_after more and more, replaced the limit filter with it and soon it will also replace the search_exists api. At that point we should make it a stable api rather than experimental.
