How can I search for every reference of God described as Father through clause or syntax search?

This answer isn't exactly what you're looking for, but you could open the Topic Guide and select the topic "God the Father (Deity)". The Related Verses section will give you a list of 58 verses relevant to the topic.
Also consider a Bible Search

I entered God in Factbook, opened the "referred to as" section and selected "father." There are 224 times where God is referred to as father in that list. Here is a screenshot:
