Functions to working with Querqy from Clojure. 

CommonRules based rewriter

{:function_score
  {:query     {:bool
                {:should   [,,,]
                 :must     [,,,]
                 :must_not [,,,]
                 :filter   []}}
   :functions [,,,]}}

Convert a `querqy.model.ExpandedQuery` into an Elasticsearch query.
You may control the query generation with the following keys in the opts map.
See the Elasticsearch documentation for their meaning.
The returned query will always be a function score query whose `:query` object
is a boolean query. The shape is:
```
{:function_score
  {:query     {:bool
                {:should   [,,,]
                 :must     [,,,]
                 :must_not [,,,]
                 :filter   []}}
   :functions [,,,]}}
```
Since this query will always be returned in this shape, you can inject
constant filter or boosting functions into the generated queries for your
domain.

The options map accepts the following values. Consult the Elasticsearch
documentation for their meaning.

- `:match/fields`
- `:match/anayzer`
- `:match/auto_generate_synonyms_phrase_query`
- `:match/fuzziness`
- `:match/max_expansions`
- `:match/prefix_length`
- `:match/fuzzy_transpositions`
- `:match/fuzzy_rewrite`
- `:match/lenient`
- `:match/operator`
- `:match/minimum_should_match`
- `:match/zero_terms_query`
- `:dis_max/tie_breaker`
