# GEOCONTAINS

The `GEOCONTAINS` field specifier (case sensitive) allows you to find documents that have a document field that describes a location region that contains a specified geometric shape.

In the following examples, the shapes used in the queries are represented by black dotted lines, and the shapes in matching documents are represented by solid green lines.

Query with... | Query results...
--- | ---
POLYGON | Polygons that contain the specified polygon. If a document field contains a multi-polygon or geometry collection, the document is returned when any part of it contains the query polygon.
LINESTRING | Polygons or lines, or multi-polygons or multi-lines, that contain the specified line.
POINT | Polygons or multi-polygons that contain the point, lines or multi-lines on which the point occurs, multi-points that contain the point, and points that exactly match the point.
MULTIPOLYGON | Polygons or multi-polygons that contain the entire MULTIPOLYGON.
MULTILINESTRING | Geometric shapes that contain all of the lines in the MULTILINESTRING.
MULTIPOINT | Geometric shapes that contain all of the points in the MULTIPOINT.
GEOMETRYCOLLECTION | Geometric shapes that contain all of the objects in the GEOMETRYCOLLECTION.

## Format

    FieldText=GEOCONTAINS{GEOMETRY}:POSITION

`GEOMETRY` | The geometric shape to query with, in Well-Known Text (WKT) format. For information about how to specify the shape, see Supported Well-Known Text Geometric Objects.
`POSITION` | The document field containing the position information. This field must contain unified geospatial location information. You can specify multiple field names, in the form `POSITION1:POSITION2:POSITION3`, and so on. A document is returned if at least one of the fields meets the requirements of the query.

NOTE: You can optimize this field specifier by configuring the position field with the GeospatialType field property.

## Example

    FieldText=GEOCONTAINS{POINT(0 0)}:LOCATION

This example matches all documents where the geospatial region described by the `LOCATION` field contains the point (0,0).
