Relation | Description | Supporting xy Field Type :--- | :--- | :--- `INTERSECTS` | (Default) Matches documents whose xy point or xy shape intersects the shape provided in the query. | `xy_point`, `xy_shape` `DISJOINT` | Matches documents whose xy shape does not intersect with the shape provided in the query. | `xy_shape` `WITHIN` | Matches documents whose xy shape is completely within the shape provided in the query. | `xy_shape` `CONTAINS` | Matches documents whose xy shape completely contains the shape provided in the query. | `xy_shape` The following examples illustrate searching for documents that contain xy shapes. To learn how to search for documents that contain xy points, see the [Querying xy points](#querying-xy-points) section. ## Defining the shape in an xy query You can define the shape in an xy query either by providing a new shape definition at query time or by referencing the name of a shape pre-indexed in another index. ### Using a new shape definition To provide a new shape to an xy query, define it in the `xy_shape` field. The following example illustrates searching for documents with xy shapes that match an xy shape defined at query time. First, create an index and map the `geometry` field as an `xy_shape`: ```json PUT testindex { "mappings": { "properties": { "geometry": { "type": "xy_shape" } } } } ``` Index a document with a point and a document with a polygon: ```json PUT testindex/_doc/1 { "geometry": { "type": "point", "coordinates": [0.5, 3.0] } } PUT testindex/_doc/2 { "geometry" : { "type" : "polygon", "coordinates" : [ [[2.5, 6.0], [0.5, 4.5], [1.5, 2.0], [3.5, 3.5], [2.5, 6.0]] ] } } ``` Define an [`envelope`]({{site.url}}{{site.baseurl}}/opensearch/supported-field-types/xy-shape#envelope)—a bounding rectangle in the `[[minX, maxY], [maxX, minY]]` format. Search for documents with xy points or shapes that intersect that envelope: ```json GET testindex/_search { "query": { "xy_shape": { "geometry": { "shape": { "type": "envelope", "coordinates": [ [ 0.0, 6.0], [ 4.0, 2.0] ] }, "relation": "WITHIN" } } } } ``` The following image depicts the example. Both the point and the polygon are within the bounding envelope. xy shape query The response contains both documents: ```json { "took" : 363, "timed_out" : false, "_shards" : { "total" : 1, "successful" : 1, "skipped" : 0, "failed" : 0 }, "hits" : { "total" : { "value" : 2, "relation" : "eq" }, "max_score" : 0.0, "hits" : [ { "_index" : "testindex", "_id" : "1", "_score" : 0.0, "_source" : { "geometry" : { "type" : "point", "coordinates" : [ 0.5, 3.0 ] } } }, { "_index" : "testindex", "_id" : "2", "_score" : 0.0, "_source" : { "geometry" : { "type" : "polygon", "coordinates" : [ [ [ 2.5, 6.0 ], [ 0.5, 4.5 ], [ 1.5, 2.0 ], [ 3.5, 3.5 ], [ 2.5, 6.0 ] ] ] } } } ] } } ``` ### Using a pre-indexed shape definition When constructing an xy query, you can also reference the name of a shape pre-indexed in another index. Using this method, you can define an xy shape at index time and refer to it by name, providing the following parameters in the `indexed_shape` object. Parameter | Description :--- | :--- index | The name of the index that contains the pre-indexed shape. id | The document ID of the document that contains the pre-indexed shape. path | The field name of the field that contains the pre-indexed shape as a path. The following example illustrates referencing the name of a shape pre-indexed in another index. In this example, the index `pre-indexed-shapes` contains the shape that defines the boundaries, and the index `testindex` contains the shapes whose locations are checked against those boundaries. First, create an index `pre-indexed-shapes` and map the `geometry` field for this index as an `xy_shape`: ```json PUT pre-indexed-shapes { "mappings": { "properties": { "geometry": { "type": "xy_shape" } } } } ``` Index an envelope that specifies the boundaries and name it `rectangle`: ```json PUT pre-indexed-shapes/_doc/rectangle { "geometry": { "type": "envelope", "coordinates" : [ [ 0.0, 6.0], [ 4.0, 2.0] ] } } ``` Index a document with a point and a document with a polygon into the index `testindex`: ```json PUT testindex/_doc/1 { "geometry": { "type": "point", "coordinates": [0.5, 3.0] } } PUT testindex/_doc/2 { "geometry" : { "type" : "polygon", "coordinates" : [ [[2.5, 6.0], [0.5, 4.5], [1.5, 2.0], [3.5, 3.5], [2.5, 6.0]] ] } } ``` Search for documents with shapes that intersect `rectangle` in the index `testindex` using a filter: ```json GET testindex/_search { "query": { "bool": { "filter": { "xy_shape": { "geometry": { "indexed_shape": { "index": "pre-indexed-shapes", "id": "rectangle", "path": "geometry" } } } } } } } ``` The preceding query uses the default spatial relation `INTERSECTS` and returns both the point and the polygon: ```json { "took" : 26, "timed_out" : false, "_shards" : { "total" : 1, "successful" : 1, "skipped" : 0, "failed" : 0 }, "hits" : { "total" : { "value" : 2, "relation" : "eq" }, "max_score" : 0.0, "hits" : [ { "_index" : "testindex", "_id" : "1", "_score" : 0.0, "_source" : { "geometry" : { "type" : "point", "coordinates" : [ 0.5, 3.0 ] } } }, { "_index" : "testindex", "_id" : "2", "_score" : 0.0, "_source" : { "geometry" : { "type" : "polygon", "coordinates" : [ [ [ 2.5, 6.0 ], [ 0.5, 4.5 ], [ 1.5, 2.0 ], [ 3.5, 3.5 ], [ 2.5, 6.0 ] ] ] } } } ] } } ``` ## Querying xy points You can also use an xy query to search for documents that contain xy points. Create a mapping with `point` as `xy_point`: ```json PUT testindex1 { "mappings": { "properties": { "point": { "type": "xy_point" } } } } ``` Index three points: ```json PUT testindex1/_doc/1 { "point": "1.0, 1.0" } PUT testindex1/_doc/2 { "point": "2.0, 0.0" } PUT testindex1/_doc/3 { "point": "-2.0, 2.0" } ``` Search for points that lie within the circle with the center at (0, 0) and a radius of 2: ```json GET testindex1/_search { "query": { "xy_shape": { "point": { "shape": { "type": "circle", "coordinates": [0.0, 0.0], "radius": 2 } } } } } ``` xy point only supports the default `INTERSECTS` spatial relation, so you don't need to provide the `relation` parameter. {: .note} The following image depicts the example. Points 1 and 2 are within the circle, and point 3 is outside the circle. xy point query The response returns documents 1 and 2: ```json { "took" : 575, "timed_out" : false, "_shards" : { "total" : 1, "successful" : 1, "skipped" : 0, "failed" : 0 }, "hits" : { "total" : { "value" : 2, "relation" : "eq" }, "max_score" : 0.0, "hits" : [ { "_index" : "testindex1", "_id" : "1", "_score" : 0.0, "_source" : { "point" : "1.0, 1.0" } }, { "_index" : "testindex1", "_id" : "2", "_score" : 0.0, "_source" : { "point" : "2.0, 0.0" } } ] } } ```
