Struggling to Set Up Search Table for Physician Practices in Clay

I am setting up my first search table based on my ICP. Having a ton of trouble getting Clay to provide me with anything useful. I am sure its because I do not understand how to use it correctly but can someone help me with a path forward? I cannot get the basic table set up. I want to search for Physician Practices (not hospitals) which are value based care organizations with 100+ APP's. Doesnt seem that tough but when I search I get a ton of hospitals and IT healthcare software companies that have no relevance to what I am doing.
