Have a separate channel for recovery, so it won't overflow the "low" channel which is also used for bulk indexing.
Also, rename the channel names to be more descriptive. Change low to bulk (for bulk based operations, currently just bulk indexing), med to reg (for "regular" operations), and high to state (for state based communication). The new channel for recovery will be named recovery, and the ping channel will remain the same.

When setting track scores, the scan search type will return the scores for each document. The Java API builder does not properly set this value (it only sets it if a sort in in place, which is not relevant for scan search type).

The description of the timeout parameter was worded misleadingly; it implied that the API would wait until the cluster reached the desired level and then stayed at that level for the timeout. I've tweaked the sentence to remove the risk of confusion.
Currently we don't allow resetting the awareness
attribute via the API since it requires at least one
non-empty string to update the setting. This commit
allows resetting this using an empty string.

The #3526 fix was not complete, it handled cases of on node execution, but didn't properly handle cases where it was executed over the network, and forcing the execution of the replica operation when done over the wire.
This relates to #3854closes#3929
Added new AckedClusterStateUpdateTask interface that can be used to submit cluster state update tasks and allows actions to be notified back when a set of (configurable) nodes have acknowledged the cluster state update. Supports a configurable timeout, so that we wait for acknowledgement for a limited amount of time (will be provided in the request as it curently happens, default 10s).
Internally, a low level AckListener is created (InternalClusterService) and passed to the publish method, so that it can be notified whenever each node responds to the publish request. Once all the expected nodes have responded or the timeoeout has expired, the AckListener notifies the action which will return adding the proper acknowledged flag to the response.
Ideally, this new mechanism will gradually replace the existing ones based on custom endpoints and notifications (per api).
Closes#3786
The suggest stop filter is an improved version of the stop filter, which
takes stopwords only into account if the last char of a query is a
whitespace. This allows you to keep stopwords, but to allow suggesting for
"a".
Example: Index document content "a word". You are now able to suggest for
"a" and get back results in the completion suggester, if the suggest stop
filter is used on the query side, but will not get back any results for
"a " as this is identified as a stopword.
The implementation allows to set the `remove_trailing` parameter for a
custom stop filter and thus use the suggest stop filter instead of the
standard stop filter.
remove usage of if and () blocks as they clashed with user paths containing ()
postpone quotation of variables to prevent double escaping ("")
fix#3906
(cherry picked from commit 1cc095ec32a5b623f88c312f497ac5469887be97)
- "boost" should be "boost_factor"
- "mult" should be "multiply"
Also, store combine function names in ImmutableMap instead of iterating
over all possible names each time.
closes#3872 for master
SynonymFilters produces token streams with stacked tokens such that
conjunction queries need to be parsed in a special way such that the
stacked tokens are added as an innner disjuncition.
Closes#3881
The array holding the payloads (TermVectorFields.payloads) is reused for each token. If the
previous token had payloads but the current token had not, then the payloads of the previous
token were returned, because the payloads of the previous token were never invalidated.
For example, for a field only contained two tokens each occurring once, the first having a
payload and the second not, then for the second token, the payload of the first was returned.
