The top_hits aggregation returned an empty InternalTopHits instance with no fields set when there were no result, causing reduce and serialization errors down the road. This is fixed by setting all required fields when a there are no results.
Closes#6346
This default type has been inherited from its ancestor, the (non-paged) recycler whose memory
usage was unbounded and required soft references to make sure it could release memory eventually.
On the contrary, the page cache recycler memory usage is bounded so we could remove soft
references in order to remove load on the garbage collector.
Note: the cache type is already randomized in integration tests.

Mustache extracts the key/value pairs for parameter substitution from
objects and maps but it's decided on the first execution. We need to
make sure if the params are null we pass an empty map to ensure we
bind the map based extractor
Closes#6318
Since plugins should never be committed to the core codebase and it is useful to be able to add plugins to the development environment adding plugins folder to the .gitignore file will stop it from appearing in the unstaged changes
At the moment plain highligher only uses an analyzer defined for on the type
level. However, during the indexing stage it is possible to define analyzer on
per document level, for example mapping '_analyzer' to another field, containing
required name. This commit attempts to make sure that highlighting works
correctly in this scenario.
Closes#5497
Because the NetworkExceptionHelper class relies on the english language in
order to extract information and decide whether a certain exception is a
network problem, we need to set the english locale on startup in order
to prevent other locales to circumvent this check.
Guava's caches have overflow issues around 32GB with our default segment
count of 16 and weight of 1 unit per byte. We give them 100MB of headroom
so 31.9GB.
This limits the sizes of both the field data and filter caches, the two
large guava caches.
Closes#6268
Because json objects are unordered this also adds an explicit order syntax
that looks like
"highlight": {
"fields": [
{"title":{ /*params*/ }},
{"text":{ /*params*/ }}
]
}
This is not useful for any of the builtin highlighters but will be useful
in plugins.
Closes#4649
When multiple date formats are specified using the || syntax in the field mappings the date_histogram aggregation breaks. This is because we are getting a parser rather than a printer from the date formatter for the object we use to convert the DateTime values back into Strings. Simple fix to get the printer from the date format and test to back it up
Closes#6239
Assertion was triggered for percolating documents with nested object
in mapping if the document did not actually contain a nested object.
Reason:
MultiDocumentPercolatorIndex checks if the number of documents is
actualu >1. Instead we can just use the SingleDocumentPercolatorIndex
in this case.
