      Description

      Currently there is an (expert) API in scorer to allow you to take a scorer, and visit its children etc (e.g. booleanquery).

      I think we should improve this, so its general to all queries.

      The current issues are:

      • the current api is hardcoded for booleanquery's Occurs, but we should support other types of children (e.g. disjunctionmax)
      • it can be difficult to use the API, because of the amount of generics and the visitor callback API.
      • the current API enforces a DFS traversal when you might prefer BFS instead.
