Colin Goodheart-Smithe 8006b105f3 Update order examples to use max instead of avg (#22032)
The use of the avg aggregation for sorting the terms aggregation is not encouraged since it has unbounded error. This changes the examples to use the max aggregation which does not suffer the same issues

markharwood aa60e5cc07 Aggregations - support for partitioning set of terms used in aggregations so that multiple requests can be done without trying to compute everything in one request.

Nik Everett 5cff2a046d Remove most of the need for `// NOTCONSOLE`
and be much more stingy about what we consider a console candidate.

* Add `// CONSOLE` to check-running
* Fix version in some snippets
* Mark groovy snippets as groovy
* Fix versions in plugins
* Fix language marker errors
* Fix language parsing in snippets

  This adds support for snippets who's language is written like
  `[source, txt]` and `["source","js",subs="attributes,callouts"]`.

  This also makes language required for snippets which is nice because
  then we can be sure we can grep for snippets in a particular language.

Adrien Grand dcc598c414 Make the heuristic to compute the default shard size less aggressive.
The current heuristic to compute a default shard size is pretty aggressive,
it returns `max(10, number_of_shards * size)` as a value for the shard size.
I think making it less aggressive has the benefit that it would reduce the
likelyness of running into OOME when there are many shards (yearly
aggregations with time-based indices can make numbers of shards in the
thousands) and make the use of breadth-first more likely/efficient.

This commit replaces the heuristic with `size * 1.5 + 10`, which is enough
to have good accuracy on zipfian distributions.

Jim Ferenczi fb2a48d0f0 Revert "Remove support for sorting terms aggregation by ascending count"
This is delayed after alpha4 since Kibana relies on it.

Colin Goodheart-Smithe cfd3356ee3 Remove size 0 options in aggregations
This removes the ability to set `size: 0` in the `terms`, `significant_terms` and `geohash_grid` aggregations for the reasons described in https://github.com/elastic/elasticsearch/issues/18838

Closes #18838

Robert Muir c5532d3df0 add a rest test for this that seems to work, fix the documentation. thanks @s1monw 2016-05-11 16:07:08 -04:00
Jim Ferenczi 052191f2a2 Add the ability to use the breadth_first mode with nested aggregations (such as `top_hits`) which require access to score information.
The score is recomputed lazily for each document belonging to a top bucket.

Colin Goodheart-Smithe 35a58d874e Scripting: Unify script and template requests across codebase
This change unifies the way scripts and templates are specified for all instances in the codebase. It builds on the Script class added previously and adds request building and parsing support as well as the ability to transfer script objects between nodes. It also adds a Template class which aims to provide the same functionality for template APIs

Closes #11091

Adrien Grand 32e23b9100 Aggs: Make it possible to configure missing values.
Most aggregations (terms, histogram, stats, percentiles, geohash-grid) now
support a new `missing` option which defines the value to consider when a
field does not have a value. This can be handy if you eg. want a terms
aggregation to handle the same way documents that have "N/A" or no value
for a `tag` field.

This works in a very similar way to the `missing` option on the `sort`
element.

One known issue is that this option sometimes cannot make the right decision
in the unmapped case: it needs to replace all values with the `missing` value
but might not know what kind of values source should be produced (numerics,
strings, geo points?). For this reason, we might want to add an `unmapped_type`
option in the future like we did for sorting.
