Layered Navigation - Basic search & Advanced Search

Hi, I have been using the layered navigation extension for a few weeks (free version)

During a "classic" search, the navigation filters are displayed normally.

For the advanced search the filters are only visible if it concerns only the name of the product. If a brand or a size is added to the search, the filters are not visible anymore.

I tried to add the layout catalogsearch_advanced_result.xml to override the default layout but it does not work.

Is it possible to have the filters on an advanced search result?

Thank you in advance for your answer.
