ElasticSearch NEST Search Multiple Types & All Fields
Your query is missing .AllTypes()
You can also specify multiple types using .Types("type1", "type1")
So:
var query = "waukesha"; // This would be passed invar resp = client.Search<dynamic>(s => s .AllTypes() .From(0) .Take(10) .Query(qry => qry .Bool(b => b .Must(m => m .QueryString(qs => qs .DefaultField("_all") .Query(query))))));
