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 less expensive 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 metadata associated with the stored geometries. Because the available
metadata 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 always returns 1.
Note
This method can not be used with geometries in round-Earth spatial reference system.
