Shape query
editShape query
editQueries documents that contain fields indexed using the shape
type.
Requires the shape
Mapping.
The query supports two ways of defining the target shape, either by providing a whole shape definition, or by referencing the name, or id, of a shape pre-indexed in another index. Both formats are defined below with examples.
Inline Shape Definition
editSimilar to the geo_shape
query, the shape
query uses
GeoJSON or
Well Known Text
(WKT) to represent shapes.
Given the following index:
PUT /example { "mappings": { "properties": { "geometry": { "type": "shape" } } } } PUT /example/_doc/1?refresh=wait_for { "name": "Lucky Landing", "geometry": { "type": "point", "coordinates": [1355.400544, 5255.530286] } }
The following query will find the point using the Elasticsearch’s
envelope
GeoJSON extension:
GET /example/_search { "query":{ "shape": { "geometry": { "shape": { "type": "envelope", "coordinates" : [[1355.0, 5355.0], [1400.0, 5200.0]] }, "relation": "within" } } } }
Pre-Indexed Shape
editThe 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:
PUT /shapes { "mappings": { "properties": { "geometry": { "type": "shape" } } } } PUT /shapes/_doc/footprint { "geometry": { "type": "envelope", "coordinates" : [[1355.0, 5355.0], [1400.0, 5200.0]] } } GET /example/_search { "query": { "shape": { "geometry": { "indexed_shape": { "index": "shapes", "id": "footprint", "path": "geometry" } } } } }
Spatial Relations
editThe following is a complete list of spatial relation operators available:
-
INTERSECTS
- (default) Return all documents whosegeo_shape
field intersects the query geometry. -
DISJOINT
- Return all documents whosegeo_shape
field has nothing in common with the query geometry. -
WITHIN
- Return all documents whosegeo_shape
field is within the query geometry.
Ignore Unmapped
editWhen 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.
