We would like to add negative search filters
In reference to #3393

[mshibuya]

Thanks for the implementation, could you add some tests for this?

[Quent1Pr]

I can't manage to run local tests by following https://github.com/railsadminteam/rails_admin/blob/master/CONTRIBUTING.md#submitting-a-pull-request

Instead, I use these commands :

appraisal install
bundle exec appraisal rake test

Please rebase against the latest master to resolve CI issues (fixed in a042aeb)

[Quent1Pr]

I add the fix. We already use the v2.x-stable in production and need this feature quickly, is it possible to stay on the 2.x-stable branch, waiting master to be stable ? In that way, we can already use our fork without breaking anything.

[mshibuya]

A new feature should go into the master first, then it can be back-ported afterwards. Can you switch target to the master branch?

[Quent1Pr]

Ok I switch to master.
Should I create a specific PR for 2.x-stable ?
