Views: attachment inherits exposed filters when set to No I created a page with an attachment to it. 
Its a Glossary for the Username.


And here is my attachment setting:

  

i Have exposed filters on the page where it is attached to:


And the Filters works together: When i write something to the name it searches it and when i click on the glossary it retains the name's search value. I don't want that. 

If i click on the Glossary i oly want that search, any other filters should reset. How do i achive that?
You can't do that by default with views settings. Filters are meant to stay upon adding / removing one of them, because otherwise you can't search items combining them. You can add a "Reset" button form the "Advanced" block of the view UI (see screenshot).



If you want this behavior to be exactly as you describe, I think you'll need write up a plugin for the filters yourself, or alter the default ones.
