Complex search within elasticsearch using NEST (.net)

Question

I am working with elasticsearch 2.3.4 (can update to 5 but its still 1 week since release and waiting for reviews on how its working)

I am trying to create asearch within my .net class

ISearchResponse<ClassModel> apiResponse = client1.Search<ClassModel>(a =>
            a.Query(q =>
            q.Term(p => p.param1, Param1) &&
            q.Term(p => p.const1, "const1") &&
            q.Term(p => p.param2, param2)));

For some reason the const1 return no values (even if i run it alone without the other params) but with HD extension i get results, maybe i shouldnt use Term ? something else?

Thank you in advance

Did you try to look at debug info in your apiReponse? There you can see query generated by NEST and you can check if the query is correct. — y0j0

It sounds as though you might not have the correct mapping on the "const1" field.

Edit as per comment below: You can use a term query on an analyzed field but it's unlikely to work how you might expect. If your field "const1" contains multiple words, then a term query with search text equal to the string you indexed will not match.

"const1": {
    "type":     "string",
    "index":    "not_analyzed"
}

A term query doesn't need the field to be not_analyzed; you can run it on an analyzed field, you just need to be aware that the term query does not analyze the input
