Max size of a string I can get from a Http.requestText request?

Hello o/

Could you give me a hand again?

What is the max size of a string that I can get from a Http.requestText request? It is truncating.

Code:

function searchGoogle(){

    text = (Http.requestText("https://script.google.com/macros/s/AmfycKwbrtui2_R9Ms-T0RdL4sQpz8QaHO7irSdggYls7GD3UV1ZS5Q/exec?param1=" + Utils.encode(star)));

}

Obs: i've changed the string of the google sheet Im accessing above because the forum is public, but it works fine, it's just truncating.

THank you very much in advance!
