Select fields on eager loading

[lfv89]

I'm already able to select the fields that will be returned from the ElasticSearch query, but now I would like to be able to select the fields that will be loaded from the database when I pass the load: true option, maybe something like:

tire.search(load: { fields: [:title] })

Can I achieve this behaviour directly trough tire ? Thank you.

@vasconcelloslf when you look at the collection class (https://github.com/karmi/tire/blob/master/lib/tire/results/collection.rb#L156) you can see that everything that you pass to :load will get propagated klass.find(ids, @options[:load])

so when you use the ActiveRecord option :select for find, it should work.

@phoet thank's for your attention.

Yep I saw that method, but I don't think that works with MongoID, I just tried Article.find(id, only: :email) and nothing... So I forked tire to make that work with MongoID... Would that be an interesting PR to make ?

@vasconcelloslf can you link the changes in there, so that @karmi can review that?

@vasconcelloslf Sorry for the silence. This is also related to #767 and effectively all discussions we're having about having a set of strategies which would allow customizable finders for major ORMs. If you have time, sure link the changes or submit a PR so we can talk around code.
