Hi,
I’m not sure if I understand correctly, but:
..do you want to display the blog posts only when the user hits the enter button on the results page?
In this case make sure to have the results override activated on the General Options -> Logic & Behavior panel: http://i.imgur.com/lGI4d7F.png
..or not to redirect at all when the enter button is used?
In this case, on the same panel, make sure that the return button & the magnifier icon events are choosen correctly: http://i.imgur.com/7rGICZO.png
It has been changed in one of the latest releases as the options were too confusing, and it is now merged into two single drop-down options.
