Based on a suggestion, we'd like to investigate if there is a way we can search a pre-set collection of projects and/or namespaces with a query string. Something that would be intuitive to users (logged in or not) and easy to use. This might be able to be done using a new button on the Special:Search page or some other method.
For instance, a logged in user might want to search for 'Kennedy' using the following project and namespaces to find documentation or maybe an older discussion or presentation:
- English Wikipedia
For additional special search bonus points - if we have the capability to do this type of search using a pre-set list of languages as well? Maybe by re-using the Compact Language links or recently used languages, but it might be preferable to use a editable configuration of these languages that the user can update/change at any time.
