Feature Request: Ability to narrow down a scene with a search

[filipemesquita]

Currently, when I submit multiple consecutive searches, bloom's default behavior is to expand the scene to show all nodes returned by any of my searchers (like a boolean OR).

In many cases, I would like to start with a more general search (e.g., all directors) and then start searches that narrow down the scene (e.g., that have directed movies after 2020), like a boolean AND.
