We have the situation that some tests fail since they don't handle
EsRejectedExecutionException which gets thrown when a node shuts
down. That is ok to ignore this exception and not fail.
We also suffer from OOMs that can't create native threads but don't
get threaddumps for those failures. This patch prints the thread
stacks once we catch a OOM which can' create native threads.
The newly added afterIndexShardPostRecovery method to InternalIndicesLifecycle, that the percolator now uses to trigger the loading of the registered queries will make sure that a shard doesn't go to started state before the queries have been loaded.
The percolate api (like other apis) will retry the execution on a different shard copy if a shard isn't in a started state preventing empty results if there registered queries to be loaded. Percolator tests fail sometimes for this reason.
The Fast Vector Highlighter can combine matches on multiple fields to
highlight a single field using `matched_fields`. This is most
intuitive for multifields that analyze the same string in different
ways. Example:
{
"query": {
"query_string": {
"query": "content.plain:running scissors",
"fields": ["content"]
}
},
"highlight": {
"order": "score",
"fields": {
"content": {
"matched_fields": ["content", "content.plain"],
"type" : "fvh"
}
}
}
}

For example when a has_child is wrapped in a filtered query as query and the wrapped filter is cached.
The short circuit mechanism in that case counts down based on deleted docs, which then yields lower results than is expected.
Relates to #4306
* Removed the applyAcceptedDocs in ChildrenConstantScoreQuery, they need to be applied at all times. (because of short circuit mechanism)
* Moved ParentDocSet to FilteredDocIdSetIterator, because it fits better than MatchDocIdSet.
* Made similar changes to ParentConstantScoreQuery for consistency between the two queries. The bug accepted docs bug didn't occur in the ParentConstantScoreQuery.
* Updated random p/c tests to randomly update parent or child docs during the test run.
Closes#4306
* Force the cat API classes to have simple help available by extending from a AbstractCatAction
* Use a set binder on guice creation to create the help on node start up
* Make sure that the help/field info is returned without querying any data
This happens when reverting the trans transaction log on failure, and when that happens, actually we might have failed on the transient translog creation to being with....
