How can i use mpr.summary.search for filtering out the data for this in jupyter notebook. I am unable to use nelements, and also has_props=bandstructure not working.
or is there anyway to exclude more than 20 elements on the site itself.

Hi @bhavuk,

Here is a code snippet to do what you want:

from mp_api.client import MPRester
from emmet.core.summary import HasProps

with MPRester("your_api_key") as mpr:
    exclude_eles = ["H", "Rb", "Cs", "Be", 
                    "Mn", "Tc", "Re", "Fe", 
                    "Ru", "Os", "Co", "Rh",
                    "Ir", "Ni", "Pd", "Pt",
                    "Ag", "Au", "Cd", "Hg"]

    docs = mpr.summary.search(num_elements=3, 
                              is_gap_direct=True,
                              exclude_elements=exclude_eles,
                              has_props=[HasProps.bandstructure],
                              fields=["material_id"])
