Create view containing all content containing taxonomy terms in free text?
If I understand correctly, you want to have one page that will display nodes grouped by taxonomy term they belong to so that the result is like this:


Term 1


article 1
article 2

Term 2


article 2
article 3

Term 3


article 1
article 3



To achieve that:


Create a view to display all content of [content type name] and select the node fields you want to display in place of article 1,2,3 (probably title of the node at least).
Add relationship "Content: Taxonomy terms on node" and decide which taxonomy you want to narrow down the display. 
Under View field, there should be now a list of Taxonomy related fields. You probably want to add field "Taxonomy term: Name". Exclude that field from display.
Under View  format settings, select to Group By that taxonomy field.
