I am trying to find out if there is a way to search for people who do not have certain tags. Is there a way to do a filtered search in order to find people who do not have a specific tags attached to them? So, if someone has the tag orange, can I do a search for all the people who do not have orange as a tag? Is there a way to do this? Thanks.
You should be able to use this in the Customers filter bar - NOT tag:orange

If you want to automate tagging, for example to automatically tag “orange” to customers that purchased a product check out Order Automator.
