Fields that Contain Coordinates within a Specified Area


The POLYGON field specifier (case sensitive) allows you to find documents whose X/Y position is within a specified polygonal shape.




are the coordinates for one of the vertices. Specify an x,y pair of coordinates for each vertex of the polygon, working either clockwise or counterclockwise around the polygon.

You can specify a concave polygon, but the edges must not cross themselves. You can specify coordinates with decimal numbers.

X is the document field that contains the X coordinate.
Y is the document field that contains the Y coordinate.

You must always specify two fields, in the order X:Y. You can specify more than one pair of fields in the form X1:Y1:X2:Y2 and so on.

For example:


This example matches all documents whose (X,Y) position is within the quadrilateral with vertices at (1,1), (–1,1), (0,–2), (1,–1).
