The ST_IntersectsFilter method provides an efficient test to determine
if two geometries might possibly intersect.
Returns 1 if the geometry-expression might intersect with geo2, otherwise 0.
This test is cheaper than ST_Intersects, but may return 1 in some cases where the geometries do
not actually intersect.
Therefore, this method can be useful as a primary filter when further processing will determine if geometries
The implementation of ST_IntersectsFilter relies upon meta-data associated with the stored geometries.
Because the available meta-data may change between server versions, depending upon how the data is loaded, or
where ST_IntersectsFilter is used within a query,
the expression geometry-expression.ST_IntersectsFilter(geo2)
can return different results when geometry-expression does not intersect
Whenever geometry-expression intersects geo2,
ST_IntersectsFilter will always return 1.
