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 ElasticsearchAPIRouter
        
        es_router = ElasticsearchAPIRouter(
            # The index or indices that your query will run.
            index_name=index_name)
        
        # Decorate a function as a filter.
        # The filter can declare parameters.
        @es_router.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.
        @es_router.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.
        @es_router.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.
        @es_router.highlighter()
        def highlight(q: Optional[str] = Query(None),
                      h: bool = Query(False):
            return {
                "name": {}
            } if q is not None and h else None
        
        # Decorate a function as a search_route. 
        # It creates a new route using the declared filters (and matchers, etc.)
        # as the endpoint parameters but combined with the route's parameters.
        @es_router.search_route("/search")
        async def search(req: Request,
                         size: Optional[int] = Query(10,
                                                     le=100,
                                                     alias="s"),
                         start_from: Optional[int] = Query(0,
                                                           alias="f"),
                         scroll: Optional[str] = Query(None),
                        ) -> JSONResponse:
            return es_router.search(
                # The elasticsearech client
                es_client=es,
                request=req,
                size=size,
                start_from=start_from,
                scroll=scroll,
            )
        
        # Include the router to your app
        app = FastAPI()
        app.include_router(es_router)
        
        ```
        
        It is possible to customize the generated query body using the decorator @search_builder.
        
        ```python
        from typing import List, Dict
        
        @es_router.search_builder()
        def build_search_body(size: int = 10,
                                        start_from: int = 0,
                                        scroll: str = None,
                                        filters: List[Dict] = [],
                                        matchers: List[Dict] = [],
                                        highlighters: List[Dict] = [],
                                        sorters: List[Dict] = []) -> Dict:
            return {
                "query": {
                    ...
                },
                ...
            }
        
        ```
