$项目里面找到mongodb

Question

It's possible to transform this:

db.processoDomain.aggregate([{
              $project: {
                'status': 1,
                'instancia': 1,
                'ano': 1,
                'numeroProcesso': 1,
                'partes': '$informacoesAdicionais.PARTES'
              }
            }])

To this:

db.processoDomain.find({}
              , {
                'status': 1,
                'instancia': 1,
                'ano': 1,
                'numeroProcesso': 1,
                'partes': '$informacoesAdicionais.PARTES'
              }
            )

Because I need to make projection in solr query, and there don't accept aggregate function.

据我所知，您要么必须将聚合管道用于其投影阶段，要么在应用程序层中使用它。
