Additional Filteroption in Resultview
Within large documentations containing multiple sources with a lot of different versions the search results are a mess. The content of different versions are still very similar and usually I got the same result for every version.
As a user I want to be able to focus my search to a specific content and version.
I suggest to add a filter button in the search result panel. This button should trigger another panel, which is displayed on top of the search results (they will be pushed down). In this panel I can select in which source and version I want to search.
