Description: # Query Utility for Elasticsearch
        
        [![Pypi](https://img.shields.io/pypi/v/fastapi-elasticsearch.svg)](https://pypi.org/project/fastapi-elasticsearch/)
        
        Utility library for creating elasticsearch query proxies using [FastAPI](https://fastapi.tiangolo.com/).
        
        ```python
        
        from fastapi_elasticsearch import ElasticsearchAPIQueryBuilder
        
        query_builder = ElasticsearchAPIQueryBuilder()
        
        # Decorate a function as a filter.
        # The filter can declare parameters.
        @query_builder.filter()
        def filter_category(c: Optional[str] = Query(None)):
            return {
                "term": {
                    "category": c
                }
            } if c is not None else None
        
        # Decorate a function as a matcher
        # (will contribute to the query scoring).
        # Parameters can also be used.
        @query_builder.matcher()
        def match_fields(q: Optional[str] = Query(None)):
            return {
                "multi_match": {
                    "query": q,
                    "fuzziness": "AUTO",
                    "fields": [
                        "name^2",
                        "description"
                    ]
                }
            } if q is not None else None
        
        # Decorate a function as a sorter.
        # Parameters can be declared.
        @query_builder.sorter()
        def sort_by(direction: Optional[str] = Query(None)):
            return {
                "name": direction
            } if direction is not None else None
        
        # Decorate a function as a highlighter.
        # Parameters can also be declared.
        @query_builder.highlighter()
        def highlight(q: Optional[str] = Query(None),
                      h: bool = Query(False):
            return {
                "name": {}
            } if q is not None and h else None
        
        app = FastAPI()
        
        # Create a route using the query builder as dependency.
        @app.get("/search")
        async def search(query_body: Dict = Depends(query_builder.build())) -> JSONResponse:
            # Search using the Elasticsearch client.
            return es.search(
                body=query_body,
                index=index_name
            )
        ```
        
        It is possible to customize the generated query body using the decorator @search_builder.
        
        ```python
        from typing import List, Dict
        
        @query_builder.search_builder()
        def build_search_body(size: int = 10,
                              start_from: int = 0,
                              source: Union[List, Dict, str] = None,
                              minimum_should_match: int = 1,
                              filters: List[Dict] = [],
                              matchers: List[Dict] = [],
                              highlighters: List[Dict] = [],
                              sorters: List[Dict] = []) -> Dict:
            return {
                "query": {
                    ...
                },
                ...
            }
        
        ```
