Multi Searchedit

The multi search API allows to execute several search requests within the same API.

Fluent DSLedit

var result = client.MultiSearch(ms => ms
    .Search<ElasticsearchProject>("projects", s => s.MatchAll())
    .Search<Person>("people", s => s.MatchAll())
);

Object Initializer Syntaxedit

var request = new MultiSearchRequest
{
    Operations = new Dictionary<string, ISearchRequest>
    {
        { "projects", new SearchRequest<ElasticsearchProject>
            {
                Query = new QueryContainer(new MatchAllQuery())
            }
        },
        { "people", new SearchRequest<Person>
            {
                Query = new QueryContainer(new MatchAllQuery())
            }
        }
    }
};

var result = client.MultiSearch(request);

Handling the Multi Search Responseedit

MultiSearch returns an IMultiSearchResponse object. Each SearchResponse<T> can be retrieved using the corresponding name that was specified in the request.

// returns a SearchResponse<ElasticsearchProject>>
var projects = result.GetResponse<ElasticsearchProject>("projects");

// returns a SearchResponse<Person>>
var people = result.GetResponse<Person>("people");
