PyMongo select fields on a full-text search

Folks,
I trying to use the fields argument on find method, I got the follow error code:

TypeError: __init__() got multiple values for keyword argument 'fields'

Code:

mongo.db.products.find({ '$text': { '$search': string } }, { 'score': { '$meta': 'textScore' } }, fields=('name', 'foo', 'bar',))

Without full-text search the fields argument works fine.

For pymongo the "projection part" for the 'textScore' needs to be included in the "fields" specification in the full form:

mongo.db.products.find(
    { '$text': { '$search': string } },
    fields=({ 'name': 1, 'foo': 1, 'bar': 1, 'score': { '$meta': 'textScore' } )
)
