The term vector API can now generate term vectors on the fly, if the terms are
not already stored in the index. This commit exploits this new functionality
for the MLT query. Now the terms are directly retrieved using multi-
termvectors API, instead of generating them from the texts retrieved using the
multi-get API.
Closes#7014
The current implementation of 'date_histogram' does not understand
the `factor` parameter. Since the docs shouldn't raise false hopes,
I removed the section.
Closes#7277
This change means that the default settings for expand_wildcards are only applied if the expand_wildcards parameter is not specified rather than being set upfront. It also adds the none and all options to the parameter to allow the user to specify no expansion and expansion to all indexes (equivalent to 'open,closed')
Closes#7258
This change stores the index creation time in the index metadata when an index is created. The creation time cannot be changed but can be set as part of the create index request to allow for correct creation times for historical data.
Closes#7119
This documentation was dangerous because it felt like it was possible to gain
substantial performance by just switching the codec of the index.
However, non-default codecs are dangerous to use since they are not supported
in terms of backward compatibility, and most improvements that they bring have
been folded into the default codec anyway (for example, the default codec
"pulses" postings lists that contain a single document).
In the case of inserts the UpdateHelper class will now allow the script used to apply updates to run on the upsert doc provided by clients. This allows the logic for managing the internal state of the data item to be managed by the script and is not reliant on clients performing the initialisation of data structures managed by the script.
Closes#7143
This adds support to return the "Access-Control-Allow-Credentials" header
if needed, so CORS will work flawlessly with authenticated applications.
Closes#6380
AND and OR filter docs talk about different targets for the operators. I
believe that both should be described in terms of modifying other 'filters'.
I also added articles for easier (human) parsing. This fixes#4762Closes#7165
Filters and Queries now supports `time_zone` parameter which defines which time zone should be applied to the query or filter to convert it to UTC time based value.
When applied on `date` fields the `range` filter and queries accept also a `time_zone` parameter.
The `time_zone` parameter will be applied to your input lower and upper bounds and will move them to UTC time based date:
[source,js]
--------------------------------------------------
{
"constant_score": {
"filter": {
"range" : {
"born" : {
"gte": "2012-01-01",
"lte": "now",
"time_zone": "+1:00"
}
}
}
}
}
{
"range" : {
"born" : {
"gte": "2012-01-01",
"lte": "now",
"time_zone": "+1:00"
}
}
}
--------------------------------------------------
In the above examples, `gte` will be actually moved to `2011-12-31T23:00:00` UTC date.
NOTE: if you give a date with a timezone explicitly defined and use the `time_zone` parameter, `time_zone` will be
ignored. For example, setting `from` to `2012-01-01T00:00:00+01:00` with `"time_zone":"+10:00"` will still use `+01:00` time zone.
Closes#3729.
Fields of type `token_count`, `murmur3`, `_all` and `_field_names` are generated only when indexing.
If a GET requests accesses the transaction log (because no refresh
between indexing and GET request) then these fields cannot be retrieved at all.
Before the behavior was so:
`_all, _field_names`: The field was siletly ignored
`murmur3, token_count`: `NumberFormatException` because GET tried to parse the values from the source.
In addition, if these fields were not stored, the same behavior occured if the fields were
retrieved with GET after a `refresh()` because here also the source was used to get the fields.
Now, GET accepts a parameter `ignore_errors_on_generated_fields` which has
the following effect:
- Throw exception with meaningful error message explaining the problem if set to false (default)
- Ignore the field if set to true
- Always ignore the field if it was not set to stored
This changes the behavior for `_all` and `_field_names` as now an Exception is thrown if a user
tries to GET them before a `refresh()`.

Allow to set the value default to network.tcp.no_delay and network.tcp.keep_alive so they won't be set at all, since on solaris, setting tcpNoDelay can actually cause failure
relates to #7115
A multi-bucket aggregation where multiple filters can be defined (each filter defines a bucket). The buckets will collect all the documents that match their associated filter.
This aggregation can be very useful when one wants to compare analytics between different criterias. It can also be accomplished using multiple definitions of the single filter aggregation, but here, the user will only need to define the sub-aggregations only once.
Closes#6118
