GEOINTERSECTS
The GEOINTERSECTS
field specifier (case sensitive) allows you to find documents that have a document field that describes a location that wholly or partially fits within a specified point or polygonal shape.
When you specify a polygon, GEOINTERSECTS
matches points that occur within the polygon, and polygon regions that at least partially overlap it. When you specify a point, GEOINTERSECTS
matches polygons that contain that point, and points that exactly match the point.
Format
FieldText=GEOINTERSECTS{POINT(coordX coordY)}:POSITION
or
FieldText=GEOINTERSECTS{POLYGON((coordX coordY, coordX coordY,...))}:POSITION
coordX coordY
|
The coordinates for a point or one of the vertices of a polygon. For a polygon, specify an X/Y pair of coordinates for each vertex, working either clockwise or counterclockwise around the polygon. The polygon can be concave, but the edges cannot cross themselves. The polygon can also contain holes. You can specify coordinates with decimal numbers. |
POSITION
|
The document field containing the position information. This field must contain unified geospatial location information (that is, Well-known text format POINT or POLYGON definitions). You can specify multiple options for the location fields, in form |
NOTE: You can optimize this field specifier by configuring the position field with the
field property.
Example
FieldText=GEOINTERSECTS{POLYGON((1 1, -1 1, 0 -2, 1 -1))}:LOCATION
This example matches all documents whose (X,Y) position is within the quadrilateral with vertices at (1,1), (-1,1), (0,-2), (1,-1). A document returns if it has a LOCATION
field that contains either a POINT definition that occurs within the specified quadrilateral, or a Well-known text POLYGON definition that at least partially overlaps it.
