Hi All,

I would like to use [Elasticsearch.Net](http://Elasticsearch.Net) (NEST requires types and I do not  
want strong types) to do a simple \_all term search. I can do this using  
the plugin elasticsearch head and I retrieve the appropriate documents.  
Here is some simple code I wrote just to say hey give me all that match.

var node = new Uri([http://myhost:9200](http://myhost:9200));

var config = new ConnectionConfiguration(node);

var exposed = config.ExposeRawResponse(true);

var client = new ElasticsearchClient(config);

var search = new

{

size = 10,

from = 1 \* 10,

query = new { query\_string = new { query = this.textBox1.Text } },

};

var searchResponse = client.Search("jdbc",search);

This returns these results:

{StatusCode: 200,  
Method: POST,  
Url: [http://u4vmeqlditapp01:9200/jdbc/\_search](http://u4vmeqlditapp01:9200/jdbc/_search),  
Request:  
{"size":10,"from":10,"query":{"query\_string":{"query":"Garrett"}}},  
Response:  
{"took":5,"timed\_out":false,"\_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":10,"max\_score":1.1672286,"hits":[]}}}

But no documents.

Here is the JSON I'm trying to replicate:

- "query": {
  - "bool": {
    - "must": [
      - {
        - "query\_string": {
          - "default\_field": "\_all",
          - "query": "Garrett"  
}  
}  
],

    - "must\_not": [],
    - "should": []  
}  
},

- "from": 0,
- "size": 25000,
- "sort": [],
- "facets": { }

I'm pretty sure it is because the query doesn't have the default\_field set  
to \_all... But I don't know how to set that. I've tried several string  
concatenations to no avail.... it just searched for them.

Any one with any ideas. I want to simply search all types for a single  
string.

{ query = this.textBox1.Text,

default\_field = "\_all"

},

This seems to send it. Still don't know how to get the results.

It's like it should be in a foreach(hit in hits) {get fields} but I have  
nothing and documentation isn't helping.

If all you need is querying, I will highly recommend looking at  
[GitHub - ElasticLINQ/ElasticLINQ: Use LINQ to query Elasticsearch with results as .NET objects](https://github.com/CenturyLinkCloud/ElasticLINQ) for .NET

I also have my own stab at a .NET client library for Elasticsearch here:  
[GitHub - synhershko/NElasticsearch: An alternative Elasticsearch client for .NET, built on-the-go while working on real-world projects](https://github.com/synhershko/NElasticsearch) /  
[NuGet Gallery | NElasticsearch 1.0.14](https://www.nuget.org/packages/NElasticsearch/1.0.14) (still WIP)

I think you are just getting unlucky. You are asking for the top 10  
results, starting \*after \*result number 10. Only problem is the search  
response is saying there is only 10 results total, so there are no hits to  
return.

Try changing your from to 0, instead of 1 \* 10. Or you can just omit that  
all together, as ES will default to 0.

If you are coming from the world of sql, one difference in simple queries  
is ES gives back the total number of results with that total property you  
see in the response's hits section. So even if you ask for only 10  
documents, total will give you the full count no matter what.

Ok that worked. Sort of. I can see the results in the response now.

However I'm not able to refer to hits. I can see them but there isn't a  
hit or hits type to refer to so I can see what is in a hit.

string? myid = searchResponse.Response.hits.hits[1].nestedObject["id"].myid  
Doesn't work.

Trying to follow this guide here  
[http://nest.azurewebsites.net/elasticsearch-net/handling-responses.html](http://nest.azurewebsites.net/elasticsearch-net/handling-responses.html)  
and hits isn't a member/method or type.

When I try to refer to hits i get this...

Error 2 'Elasticsearch.Net.DynamicDictionary' does not contain a definition  
for 'hits' and no extension method 'hits' accepting a first argument of  
type 'Elasticsearch.Net.DynamicDictionary' could be are you missing a using

Getting closer:

I converted my searchResponse to a var

i can now refer to a value like this:

(((dynamic)dyndist).hits.hits[1]).Value.\_source.Id  
This works great and if I put a 2 there it works and returns the second  
item.

Ok that's all well and good however. I cannot do something like this:

var dyndist = new Elasticsearch.Net.DynamicDictionary();  
dyndist = searchResponse.Response;  
long maxhit;  
maxhit = ((dynamic)dyndist).hits.total.Value; //this does get the # of hits  
for (int hitpos = 1 ; hitpos \<= maxhit; hitpos ++)  
{  
//just creating a string here but I would  
theid = theid + ":" +  
(((dynamic)dyndist).hits.hits[hitpos]).Value.\_source.Id; //id is my id not  
the id from Elasticsearch  
}

I get this error:

An unhandled exception of type  
'Microsoft.CSharp.RuntimeBinder.RuntimeBinderException' occurred in  
System.Core.dll  
Additional information: Cannot perform runtime binding on a null reference

If I switch that hitpos to a 1 it works fine and returns the 1 value. i  
want to get them all somehow..

Any ideas.

I tried converting to a List but only .Values is a List seems I can't  
convert hits.hits. Stuck here for now ☹
