Implement search form (#8103)

* Add UI for advanced search
To help users with the seach operators.
Obviously not as powerful as a manually-written search query.
Lack in particular negation and logical *and* for now, but I might try to do something about it.

* Consistency: allow multiple user queries like S:1,2

* Fix user query and add tests
