ReQL command: intersects

Command syntax

sequence.intersects(geometry) → sequence
geometry.intersects(geometry) → bool
r.intersects(sequence, geometry) → sequence
r.intersects(geometry, geometry) → bool

Description

Tests whether two geometry objects intersect with one another. When applied to a sequence of geometry objects, intersects acts as a filter, returning a sequence of objects from the sequence that intersect with the argument.

Example: Is point2 within a 2000-meter circle around point1?

> point1 = r.point(-117.220406,32.719464)
> point2 = r.point(-117.206201,32.725186)
> r.circle(point1, 2000).intersects(point2).run(conn)

true

Example: Which of the locations in a list of parks intersect circle1?

circle1 = r.circle([-117.220406,32.719464], 10, {:unit => 'mi'})
r.table('parks')('area').intersects(circle1).run(conn)

The intersects command cannot take advantage of a geospatial secondary index. If you’re working with large data sets, you should consider using an index and the get_intersecting command instead of intersects.
