Anyone familiar with the twitter API

if i'm using my access tokens to get into the network, is the information i receive from things that are presented to me by twitter's algorithm [and therefore essentially biased according to my own interactions with it], or would I get the same results regardless of who's access tokens are used?

if i tell my program to search a string, will it search all twitter, or only a subset based on the access tokens?

Apparently it depends on the token and what you're using it for, check this https://dev.twitter.com/oauth/overview and this https://dev.twitter.com/oauth/overview/single-user The only way to know if tbe search results have a bias, is to test it with another account and see.

Thank you, I considered running two different tokens at the same time, but concluded that they could still show very different results even if they were pulling material from the same stream.

I doubt either would get all of it.
