Create Search API endpoint

[TeddyCr]

Context

Engage is working on developing a search functionality to improve the UI experience of its user. We'll use elastic search to enable users to narrow down agenda items to a specific topic.

Dependencies

• Issue Create flow to index new agenda items to Elasticsearch index #174

To-Dos

• Create backend API endpoint to query and search indexed agenda items*.

*backend endpoint should be added to the backend.engage.town/api/.... part of the site.
The API endpoint should accept search terms passed by the client ([...].engage.town), send a structured request to the Elasticsearch search endpoint and return the response from the Elasticsearch endpoint.

Elasticsearch search endpoint request body

{
    "query": {
        "multi_match": {
            "query": "my search term",
            "type": "most_fields",
            "fields": ["meeting_title^2", "meeting_recommendations", "meeting_body"],
            "fuzziness": "AUTO"
        }
     }
}

The nice thing about elastic search is you can open the querying up to the world and only have adding locally accessible. That way you don't need a backend endpoint, just the HTTP queries to elasticsearch.
