## Name

&&&(gidx,geometry) — Returns `TRUE`

if a n-D float precision bounding box (GIDX) intersects a geometry's (cached) n-D bounding box.

## Synopsis

`boolean `**&&&**(

gidx
`A`
,
geometry
`B`
`)`

;

## Description

The `&&&`

operator returns `TRUE`

if the n-D bounding box A intersects the cached n-D bounding box of geometry B, using float precision. This means that if A is a (double precision) box3d, it will be internally converted to a float precision 3D bounding box (GIDX)

This operator is intended to be used internally by BRIN indexes, more
than by users. |

Availability: 2.3.0 support for Block Range INdexes (BRIN) was introduced. Requires PostgreSQL 9.5+.

This method supports Circular Strings and Curves.

This function supports Polyhedral surfaces.

This function supports Triangles and Triangulated Irregular Network Surfaces (TIN).

This function supports 3d and will not drop the z-index.

## Examples
