Search on field party into the form customer invoice or supplier invoice not work

When I try to use filters “Party: !=cooper” into the form customer invoice for example, this search did not work.

Can I use this filter in these forms?

What is not working? Are you talking about Issue 8477: Wrong filtering with 'Party:!anytext' in Invoices, Sale, Purchase - Tryton issue tracker ?

I did not see this issue, sorry. This issue: will include in next release maybe?

Only if someone provides a patch.
