Implement a new sort method for FindOptions that accepts a Meta and a Sort args

[josephcaroe]

So my problem is related to a query that performs a text search. After the text search is done, I want to sort the results by the Meta score "textScore", so I use the sort method of the FindOptions class that accepts a Meta argument. But in native mongo, it's possible to also sort by another field, in case scores have the same values. The problem is you can't add another sort field if you use the sort method that accepts the Meta parameter.

I'd like to have a way to specify both sorting options: sort by textScore, and the sort by another field.

I can sort after the query is done, using java Comparators, but it's a pity something you can actually do in native mongo can't be replicated in morphia.

Mongo query that works, with sort options (one is the Meta score, the other is another field:

   db.phenotypes
      .find(
         { $text: {$search: "abnormal"} },
         { score:{$meta: "textScore"} })
      .sort(
         { score:{$meta:"textScore"} },
         { name:1 })
      .limit(10)
