The ST_ContainsFilter method provides an efficient test to determine if one geometry might contain the other.
Returns 1 if the geometry-expression might contain geo2, otherwise 0.
This test is cheaper than ST_Contains, but may return 1 in some cases where
the geometry-expression does not actually contain geo2.
Therefore, this method can be useful as a primary filter when further processing will determine whether geometries
interact in the desired way.
The implementation of ST_ContainsFilter 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_ContainsFilter is used within a query,
the expression geometry-expression.ST_ContainsFilter(geo2)
can return different results when geometry-expression does not contain
geo2.
Whenever geometry-expression contains geo2,
ST_ContainsFilter will always return 1.
Note
This method can not be used with geometries in round-Earth spatial reference system.
