   > Are the coordinates of your polygons in lon/lat degrees? If this is the 
case, you should use `ST_DistanceSphere` or `ST_DWithin(a.polygon_geometry, 
b.polygon_geometry, 100, true)` to calculate the spherical distance. Otherwise, 
the distance calculated by ST_Distance will be in degrees, which could result 
in a significantly large result set for the join.
   
   Do you mean the WHERE condition or the distance in the SELECT statement?
