Webpage search clarifications

Hi all,

I have a few questions regarding the search on the materialsproject.org website:

  1. What is the difference between the ICSD and Expt. ICSD tick boxes, and more importantly how are the values related to the icsd_ids property?
  2. Is it possible to search for all compounds containing an element. For example, using “Fe-*” as a search string returns only binary compounds, while “*-Fe-*” returns tertiary compounds.
