Christoph Büscher 4f5a83dba2 Clarify using time_zone and date math in range query (#40655)
Currently, the docs correctly state that using `now` in range queries will not
be affected by the `time_zone` parameter. However, using date math roundings
like e.g. `now\d` will be affected by the `time_zone`. Adding this example
because it seems to be a frequently asked question and source of confusion.

Mayya Sharipova 24755209b4 Add randomScore function in script_score query (#40186)
To make script_score query to have the same features
as function_score query, we need to add randomScore
function.

This function produces different
random scores on different index shards.
It is also able to produce random scores
based on the internal Lucene Document Ids.

search as you type fieldmapper (#35600)
Adds the search_as_you_type field type that acts like a text field optimized
for as-you-type search completion. It creates a couple subfields that analyze
the indexed terms as shingles, against which full terms are queried, and a
prefix subfield that analyze terms as the largest shingle size used and
edge-ngrams, against which partial terms are queried

Adds a match_bool_prefix query type that creates a boolean clause of a term
query for each term except the last, for which a boolean clause with a prefix
query is created.

The match_bool_prefix query is the recommended way of querying a search as you
type field, which will boil down to term queries for each shingle of the input
text on the appropriate shingle field, and the final (possibly partial) term
as a term query on the prefix field. This field type also supports phrase and
phrase prefix queries however

Make the `type` parameter optional when percolating existing documents. (#39987) (#39989)
`document_type` is the type to use for parsing the document to percolate, which

ability to percolate existing documents, identified by an index, an id and a
type. This change makes the latter optional and deprecated.

Track total hits up to 10,000 by default (#37466)
This commit changes the default for the `track_total_hits` option of the search request
to `10,000`. This means that by default search requests will accurately track the total hit count
up to `10,000` documents, requests that match more than this value will set the `"total.relation"`
to `"gte"` (e.g. greater than or equals) and the `"total.value"` to `10,000` in the search response.
Scroll queries are not impacted, they will continue to count the total hits accurately.
The default is set back to `true` (accurate hit count) if `rest_total_hits_as_int` is set in the search request.
I choose `10,000` as the default because that's also the number we use to limit pagination. This means that users will be able to know how far they can jump (up to 10,000) even if the total number of hits is not accurate.

Remove remaining occurances of "include_type_name=true" in docs (#37646) 2019-01-22 15:13:52 +01:00
Christoph Büscher 25aac4f77f
Remove `include_type_name` in asciidoc where possible (#37568)
The "include_type_name" parameter was temporarily introduced in #37285 to facilitate
moving the default parameter setting to "false" in many places in the documentation
code snippets. Most of the places can simply be reverted without causing errors.
In this change I looked for asciidoc files that contained the
"include_type_name=true" addition when creating new indices but didn't look
likey they made use of the "_doc" type for mappings. This is mostly the case
e.g. in the analysis docs where index creating often only contains settings. I
manually corrected the use of types in some places where the docs still used an
explicit type name and not the dummy "_doc" type.

Update the default for include_type_name to false. (#37285)
* Default include_type_name to false for get and put mappings.

* Default include_type_name to false for get field mappings.

* Add a constant for the default include_type_name value.

* Default include_type_name to false for get and put index templates.

* Default include_type_name to false for create index.

* Update create index calls in REST documentation to use include_type_name=true.

* Some minor clean-ups around the get index API.

* In REST tests, use include_type_name=true by default for index creation.

* Make sure to use 'expression == false'.

* Clarify the different IndexTemplateMetaData toXContent methods.

* Fix FullClusterRestartIT#testSnapshotRestore.

* Fix the ml_anomalies_default_mappings test.

* Fix GetFieldMappingsResponseTests and GetIndexTemplateResponseTests.

We make sure to specify include_type_name=true during xContent parsing,
so we continue to test the legacy typed responses. XContent generation
for the typeless responses is currently only covered by REST tests,
but we will be adding unit test coverage for these as we implement
each typeless API in the Java HLRC.

This commit also refactors GetMappingsResponse to follow the same appraoch
as the other mappings-related responses, where we read include_type_name
out of the xContent params, instead of creating a second toXContent method.
This gives better consistency in the response parsing code.

* Fix more REST tests.

* Improve some wording in the create index documentation.

* Add a note about types removal in the create index docs.

* Fix SmokeTestMonitoringWithSecurityIT#testHTTPExporterWithSSL.

* Make sure to mention include_type_name in the REST docs for affected APIs.

* Make sure to use 'expression == false' in FullClusterRestartIT.

* Mention include_type_name in the REST templates docs.

[Geo] Integrate Lucene's LatLonShape (BKD Backed GeoShapes) as default `geo_shape` indexing approach (#36751)
* [Geo] Expose BKDBackedGeoShapes as new VECTOR strategy

This commit exposes lucene's LatLonShape field as a new
strategy in GeoShapeFieldMapper. To use the new indexing
approach, strategy should be set to "vector" in the
geo_shape field mapper. If the tree parameter is set
the mapper will throw an IAE. Note the following:

When using vector strategy:

* geo_shape query does not support querying by POINT,
MULTIPOINT, or GEOMETRYCOLLECTION.
* LINESTRING and MULTILINESTRING queries do not support
WITHIN relation.
* CONTAINS relation is not supported.
* The tree, precision, tree_levels, distance_error_pct,
and points_only parameters will not throw an exception
but they have no effect and will be marked as
deprecated..

All other features are supported.

* revert change to PercolatorFieldMapper

* fix ExistsQuery for geo_shape vector strategy

* add deprecation logging for tree, precision, tree_levels, distance_error_pct, and points_only

* initial update to geoshape docs, including mapping migration updates

* initial support for GeoCollection queries

* fix docs and javadoc errors

* clean up geocollection queries

* set deprecated mapping tests to NOTCONSOLE

* fix geo-shape mapper asciidoc mapping and test warnings

* add support for point queries using LatLonShapeBoundingBoxQuery

* update GeoShapeQueryBuilderTests to include POINT queries for VECTOR strategy. Other comment cleanups

* add lucene geometry build testing to ShapeBuilder tests

* remove deprecated prefix tree mapping from geo-shape.asciidoc

* refactor GeoShapeFieldMapper into LegacyGeoShapeFieldMapper and GeoShapeFieldMapper

Both classes derive from BaseGeoShapeFieldMapper that provides shared parameters:
coerce, ignoreMalformed, ignore_z_value, orientation.

* update docs to remove vector strategy

* fix GeometryCollectionBuilder#buildLucene to return the object created by the shape builder

* fix LineLength failure in GeoJsonShapeParserTests

* ShapeMapper refactor changes from PR feedback

* fix typo in geo-shape.asciidoc

* ignore circle test in docs

* update indexing-approach ref to geoshape-indexing-approach

* add warnings check for LegacyGeoShapeFieldMapper to AbstractBuilderTestCase

* fix deprecatedParameters setup

* update indexing approach

* fixing unexpected warnings failures

* move orientation back to field type

* remove if in LegacyGeoShapeFieldMapper#doXContent. Fix GeoShapeFieldMapper to work with double array as a point

* fix indexing-approach link in circle section of geoshape docs

* add strategy to deprecation warnings check

* fix test failures

* fix typo in QueryStringQueryBuilderTests

* fix total hits to totalHits().value

* fix version number

* add version check to BaseGeoShapeFieldMapper

* fix line length!

This commit  exposes lucene's LatLonShape field as the

Make hits.total an object in the search response (#35849)
This commit changes the format of the `hits.total` in the search response to be an object with
a `value` and a `relation`. The `value` indicates the number of hits that match the query and the
`relation` indicates whether the number is accurate (in which case the relation is equals to `eq`)
or a lower bound of the total (in which case it is equals to `gte`).
This change also adds a parameter called `rest_total_hits_as_int` that can be used in the
search APIs to opt out from this change (retrieve the total hits as a number in the rest response).
Note that currently all search responses are accurate (`track_total_hits: true`) or they don't contain
`hits.total` (`track_total_hits: true`). We'll add a way to get a lower bound of the total hits in a
follow up (to allow numbers to be passed to `track_total_hits`).

Remove the distinction between query and filter context in QueryBuilders (#35354)
When building a query Lucene distinguishes two cases, queries that require to produce a score and queries that only need to match. We cloned this mechanism in the QueryBuilders in order to be able to produce different queries based on whether they need to produce a score or not. However the only case in es that require this distinction is the BoolQueryBuilder that sets a different minimum_should_match when a `bool` query is built in a filter context..
This behavior doesn't seem right because it makes the matching of `should` clauses different when the score is not required.

            },
            "min_score" : 2
        }
    }
}
```

Add several functions to painless to be used inside script_score:

double rational(double, double)
double sigmoid(double, double, double)
double randomNotReproducible() 
double randomReproducible(String, int) 

double decayGeoLinear(String, String, String, double, GeoPoint)
