      The Search team recently released support for explain() as a beta for $search queries.

      I gave it a quick try and noticed that we are not expanding some of the objects in the explain plan output (see screenshots).

      We should fix that.

      To test this, I created a search index on the sample_mflix.movies collection in our test cluster. Here are a couple of explain examples:

      use('sample_mflix');
      db.movies.explain("executionStats").aggregate([{
          $search: {
            index: 'mflix-movies-fts',
            text: {
              query: 'Kill',
              path: 'title',
              fuzzy: {}
            }
          }
        },
        {
          /**
           * specifications: The fields to
           *   include or exclude.
           */
          $project: {
            _id: 0,
            title: 1
          }
        }
      ]);
      
      use('sample_mflix');
      db.movies.explain("queryPlanner").aggregate([{
          $search: {
            index: 'mflix-movies-fts',
            text: {
              query: 'Kill',
              path: 'title'
            }
          }
        },
        {
          /**
           * specifications: The fields to
           *   include or exclude.
           */
          $project: {
            _id: 0,
            title: 1
          }
        }
      ]);
