Requesting to many docvalue_fields in a search request can potentially be costly
because it might incur a per-field per-document seek. This change introduces a
soft limit on the number of fields that can be retrieved. The setting can be
changed per index using the `index.max_docvalue_fields_search` setting.
Relates to #26390
You can define a proxy using the following settings:
```yml
azure.client.default.proxy.host: proxy.host
azure.client.default.proxy.port: 8888
azure.client.default.proxy.type: http
```
Supported values for `proxy.type` are `direct`, `http` or `socks`. Defaults to `direct` (no proxy).
Closes#23506
BTW I changed a test `testGetSelectedClientBackoffPolicyNbRetries` as it was using an old setting name `cloud.azure.storage.azure.max_retries` instead of `azure.client.azure1.max_retries`.
Follow up for #23405.
We remove azure deprecated settings in 7.0:
* The legacy azure settings which where starting with `cloud.azure.storage.` prefix have been removed.
This includes `account`, `key`, `default` and `timeout`.
You need to use settings which are starting with `azure.client.` prefix instead.
* Global timeout setting `cloud.azure.storage.timeout` has been removed.
You must set it per azure client instead. Like `azure.client.default.timeout: 10s` for example.
* Limit the number of expanded fields it query_string and simple_query_string
This limits the number of automatically expanded fields for the "all fields"
mode (`"default_field": "*"`) for the `query_string` and `simple_query_string`
queries to 1024 fields.
Resolves#25105
* Add blurb about limit to the docs
The percolator will add a `_percolator_document_slot` field to all percolator
hits to indicate with what document it has matched. This number matches with
the order in which the documents have been specified in the percolate query.
Also improved the support for multiple percolate queries in a search request.
This change exposes the duplicate removal option added in Lucene for the completion suggester
with a new option called `skip_duplicates` (defaults to false).
This commit also adapts the custom suggest collector to handle deduplication when multiple contexts match the input.
Closes#23364
The current "Building Queries" and "Building Aggregations" pages are
located under the "Supported Apis" section because they are linked to
the "Search API" page.
It should instead be in a dedicated section: this commit adds a new
"Using Java Builders" section and renames few filenames in favor of
more meaningful names.
The `index.percolator.map_unmapped_fields_as_text` is a more better name, because unmapped fields are mapped to a text field with default settings
and string is no longer a field type (it is either keyword or text).
The definition of development vs. production mode has evolved slightly
over time (with the introduction of single-node) discovery. This commit
clarifies the documentation to better account for this adjustment.
Relates #26460
Adding a check to QueryStringQueryBuilderTests that checks the override
behaviour of `quote_analyzer`, also adding documentation explaining the use of
this parameter in `query_string` query.
Closes#25417
The current script service has a script compilation limit for a one
minute window. This is set to a small default value of 15. Instead of
increasing that default value, this commit introduces a new setting
that allows to configure a rate per time unit, so that the script service can deal with bursts better.
The new setting is named `script.max_compilations_rate`,
requires a nonnegative number and a positive time value.
The default is `75/5m`, which is equivalent to the existing 15 per minute.
Multi-level Nested Sort with Filters
Allow multiple levels of nested sorting where each level can have it's own filter.
Backward compatible with previous single-level nested sort.
* Remove the _all metadata field
This change removes the `_all` metadata field. This field is deprecated in 6
and cannot be activated for indices created in 6 so it can be safely removed in
the next major version (e.g. 7).
At current, we do not feel there is enough of a reason to shade the low
level rest client. It caused problems with commons logging and IDE's
during the brief time it was used. We did not know exactly how many
users will need this, and decided that leaving shading out until we
gather more information is best. Users can still shade the jar
themselves. For information and feeback, see issue #26366.

587409e893 introduced a bug where an example of the format of a request which contained placeholder values was attempted to be tested. This change adds `NOTCONSOLE` to that snippet as the immediately following snippet tests a concrete example.
220212dd69 introduced a bug because the test substitution was looking for `otherhost` where the snippet contained `oldhost`. This change fixes the substitution
By making RestHighLevelClient Closeable, its close method will close the internal low-level REST client instance by default, which simplifies the way most users interact with the high-level client.
Its constructor accepts now a RestClientBuilder, which clarifies that the low-level REST client is internally created and managed.
It is still possible to provide an already built `RestClient` instance, but that can only be done by subclassing `RestHighLevelClient` and calling the protected constructor that accepts a `RestClient`. In such case a consumer has also to be provided, which controls what has to be done when the high-level client gets done.
Closes#26086
* Accept an array of field names and boosts in the index.query.default_field setting
This commit allows to define an array of field names and boosts for the index setting `index.query.default_field`.
The format is equivalent to the `fields` options of the full text search queries (e.g. field_name^boost).
This commit also makes this setting dynamically updatable.
Fixes#25946
* Deprecate global_ordinals_hash and global_ordinals_low_cardinality
This change deprecates the `global_ordinals_hash` and `global_ordinals_low_cardinality` and
makes the `global_ordinals` execution hint choose internally if global ords should be remapped or use the segment ord directly.
These hints are too sensitive and expert to be exposed and we should be able to take the right decision internally based on the agg tree.
Currently the `precision` parameter must be a precision level
in the range of [1,12]. In #5042 it was suggested also supporting
distance units like "1km" to automatically approcimate the needed
precision level. This change adds this support to the Rest API by
making use of GeoUtils#geoHashLevelsForPrecision.
Plain integer values without a unit are still treated as precision
levels like before. Distance values that are too small to be represented
by a precision level of 12 (values approx. less than 0.056m) are
rejected.
Closes#5042
There was some confusion about the fact that tokens emitted from a Pattern
Capture Token Filter are treated as synonyms when used to analyze a search
query. This commit adds an explanation to the note in the docs to emphasize this
behaviour.
Closes#25746
This change is a continuation of #25726 that aligns field expansions for the simple_query_string with the query_string and multi_match query.
The main changes are:
* For exact field name, the new behavior is to rewrite to a matchnodocs query when the field name is not found in the mapping.
* For partial field names (with * suffix), the expansion is done only on keyword, text, date, ip and number field types. Other field types are simply ignored.
* For all fields (*), the expansion is done on accepted field types only (see above) and metadata fields are also filtered.
The use_all_fields option is deprecated in this change and can be replaced by setting `*` in the fields parameter.
This commit also changes how text fields are analyzed. Previously the default search analyzer (or the provided analyzer) was used to analyze every text part
, ignoring the analyzer set on the field in the mapping. With this change, the field analyzer is used instead unless an analyzer has been forced in the parameter of the query.
Finally now that all full text queries can handle the special "*" expansion (`all_fields` mode), the `index.query.default_field` is now set to `*` for indices created in 6.
