0e4517d901 Combine search, facet and sort fields into a single "fields". 
1. All numerical fields are added to sort index automatically since that makes logical sense.
2. Search fields to be used as a facet are to have a `facet: true` property - removes duplication.
3. If someone wants to use a faceted field also to search against (rare scenario), then they can duplicate that field without the `facet: true` property.
