Add facets to filter merge requests by repository it was forked from
Problem to solve
This is an issue for implementing #385568 at /search
It can be useful find out how many merge and which merge requests came from a specific fork. In @nick_vh 's case, https://gitlab.com/gitlab-community/gitlab as this is used to allow contributors to collaborate. But it's not easy to find the MRs that originated from this fork.
Proposal
We should add this filter to /search
as a facet (source_project_id
field). We can start with implementing backend, so it can be at least used via the query parameter until frontend is implemented.
