Retrieving only entries that match experimentally-determined crystal structure.

[fedeotto]

Hello,

I'm trying to find in the documentation a way to query all entries that match experimentally-determined crystal structure. I'm interested in band gap and formation energy, and made a query like this:

with MPRester("api_key") as mpr:

    entries= mpr.query(criteria = {"band_gap" : {"$gt":0.5}}, properties = ["band_gap", "formation_energy_per_atom"])

Is it possible to add something in the above code to fulfil my request?

Many thanks
