Feature Request: Filter scoring

[frellan]

Add support for filter scoring. Feels like a must have for any more involved application. If you select one or more attributes you want present in an array in the documents, you certainly want the search results to be sorted based on how many of your requests are fulfilled by each item. If this is already present in the existing rules somehow and the solution is obvious then I apologize.

Here are the relevant docs from algolia:
