Previously, one MLT query per field was created for each item. One issue with
this method is that the maximum number of selected terms was equal to the
number of items times 'max_query_terms'. Instead, users should have direct control
over the maximum number of selected terms allowed, regardless of the number of
queried items.
Another issue related to the previous method is that it could lead to the
selection of rather uninteresting terms, that because they were found in a
particular queried item. Instead, this new procedure enforces the selection of
interesting terms across ALL items, not within each item. This could lead to
search results where the best matching items share commonalities amongst the
best characteristics of all the items.

This commit adds checks for nocommit and tabs in the source code.
The task is executed during the validate phase and can be disabled via
`-Dvalidate.skip`
* `english` returned the slow snowball English stemmer
* `porter2` returned the snowball Porter stemmer (v1)
* `portuguese` was used twice, preventing the second version from working
Changes:
* `english` now returns the fast PorterStemmer (for indices created from v1.3.0 onwards)
* `porter2` now returns the snowball English stemmer (for indices created from v1.3.0 onwards)
* `light_english` now returns the `kstem` stemmer (`kstem` still works)
* `portuguese_rslp` returns the PortugueseStemmer
* `dutch_kp` is a synonym for `kp`
Tests and docs updated
Fixes#6345Fixes#6213Fixes#6330
Bugs:
* "groups" and "types" were being ignored
* "completion_fields" as wildcards were not being resolved to fieldnames
Enhancements:
* Made "groups" and "types" support wildcards
* Added missing tests
Closes#6390
In order to return more information to the client, in case a TransportClient
can not connect to the cluster, this commit adds logging and also returns the
configured nodes in the NoNodeAvailableException
Also a minor bug has been fixed, which propagated exceptions wrong, so that an
invalid request was actually tried on every node, if a regular connection failure
on the first node had happened.
Closes#6376
Our REST backwards compatibility tests need to be able to disable client nodes within the TestCluster when running older tests that assume client nodes are not around.
Previously if the user provided a non-conforming string, it would blow up with
`java.lang.StringIndexOutOfBoundsException: String index out of range: -1`
which is not a *helpful* error message.
Also updated the documentation to make the possible setting values more clear.

A new "breadth_first" results collection mode allows upper branches of aggregation tree to be calculated and then pruned
to a smaller selection before advancing into executing collection on child branches.
Closes#6128
The put index template api supports the create parameter (defaults to false), which tells whether the template can replace an existing one with same name or not. Unified its behaviour between PUT and POST method, whereas the POST would previously force create to true.
Added create parameter to the rest spec (was missing before) and a REST test for create true scenario.
There is a pretty nasty bug in the lock factory we use that can cause
nodes to use the same data dir wiping each others data. Luckily this is
unlikely to happen if the nodes are running in different JVM which they
do unless they are embedded.

E.g. we use Unsafe in quite a few places and this generates lots of
warnings, which we now suppress using the undocumented
-XDignore.symbol.file command-line option to javac.
Closes#6423
The existing Note about the shorthand suggest syntax was poorly worded and confusing. Please check whether the way I've phrased it now is still correct as to what the shorthand form actually does and doesn't do: the original wording did not provide me enough information to be sure.
Thanks!
