Short description and why it's useful

There's currently no way to customize which fields to search with, neither the weights (boost) for each field, nor fuzziness (misspelling) or custom scoring functions . The default query uses a "match_phrase_prefix" operator which is usually used as autocomplete-like feature, but lacks of some key Elastic key features like: fuzziness, custom scoring, misspelling (for instance if your query term is "Hodie" instead of "Hoodie", you'll get no results), etc.

We have made a few modifications so all these features can be customized via configuration file, giving the ability to make the search query more dynamic and powerful than the current functionality. It is now possible to define the searchable fields, how to sort them by attribute values, added fuzziness (for misspelling) an ability to add custom weights (boosts) to both function_score and attributes individually.
