Filter documents indexed using the `geo_shape` type.
Requires the <<geo-shape,`geo_shape` Mapping>>.
The `geo_shape` query uses the same grid square representation as the
`geo_shape` mapping to find documents that have a shape that intersects
[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.

with the query shape. It will also use the same Prefix Tree configuration
as defined for the field mapping.
The query supports two ways of defining the query shape, either by
providing a whole shape definition, or by referencing the name of a shape
pre-indexed in another index. Both formats are defined below with
examples.
==== Inline Shape Definition
Similar to the `geo_shape` type, the `geo_shape` query uses
http://www.geojson.org[GeoJSON] to represent shapes.
Given the following index:
[source,console]
--------------------------------------------------
PUT /example
{
"mappings": {
"properties": {
"location": {
"type": "geo_shape"
}
}
}
}
POST /example/_doc?refresh
{
"name": "Wind & Wetter, Berlin, Germany",
"location": {
"type": "point",
"coordinates": [13.400544, 52.530286]
}
}
--------------------------------------------------
// TESTSETUP
The following query will find the point using the Elasticsearch's
`envelope` GeoJSON extension:
[source,console]
--------------------------------------------------
GET /example/_search
{
"query":{
"bool": {
"must": {
"match_all": {}
},
"filter": {
"geo_shape": {
"location": {
"shape": {
"type": "envelope",
"coordinates" : [[13.0, 53.0], [14.0, 52.0]]
},
"relation": "within"
}
}
}
}
}
}
--------------------------------------------------
==== Pre-Indexed Shape
The Query also supports using a shape which has already been indexed in
another index. This is particularly useful for when
you have a pre-defined list of shapes which are useful to your
application and you want to reference this using a logical name (for
example 'New Zealand') rather than having to provide their coordinates
each time. In this situation it is only necessary to provide:
* `id` - The ID of the document that containing the pre-indexed shape.
* `index` - Name of the index where the pre-indexed shape is. Defaults
to 'shapes'.
* `path` - The field specified as path containing the pre-indexed shape.
Defaults to 'shape'.
* `routing` - The routing of the shape document if required.
The following is an example of using the Filter with a pre-indexed
shape:
[source,console]
--------------------------------------------------
PUT /shapes
{
"mappings": {
"properties": {
"location": {
"type": "geo_shape"
}
}
}
}
PUT /shapes/_doc/deu
{
"location": {
"type": "envelope",
"coordinates" : [[13.0, 53.0], [14.0, 52.0]]
}
}
GET /example/_search
{
"query": {
"bool": {
"filter": {
"geo_shape": {
"location": {
"indexed_shape": {
"index": "shapes",
"id": "deu",
"path": "location"
}
}
}
}
}
}
}
--------------------------------------------------
==== Spatial Relations
The <<spatial-strategy, geo_shape strategy>> mapping parameter determines
which spatial relation operators may be used at search time.
The following is a complete list of spatial relation operators available:
* `INTERSECTS` - (default) Return all documents whose `geo_shape` field
intersects the query geometry.
* `DISJOINT` - Return all documents whose `geo_shape` field
has nothing in common with the query geometry.
* `WITHIN` - Return all documents whose `geo_shape` field
is within the query geometry.
* `CONTAINS` - Return all documents whose `geo_shape` field

contains the query geometry. Note: this is only supported using the
`recursive` Prefix Tree Strategy deprecated[6.6]
[float]
==== Ignore Unmapped
When set to `true` the `ignore_unmapped` option will ignore an unmapped field
and will not match any documents for this query. This can be useful when
querying multiple indexes which might have different mappings. When set to
`false` (the default value) the query will throw an exception if the field
is not mapped.
