Typical traditional search fund Buy-Side Referral Fee Agreement

Hi all,
As I am starting my search, I will sign bunch of buy-side referral fee agreements. What are the typical terms you see? and most importantly what is the typical % of "consideration" paid and min. fixed $ (e.g. max of $x k and y% of Consideration)

what is typical x and y here? Lastly, consideration meaning deal value, is it equity paid or total EV paid?

THANK YOU all!
