Hello All,

I want to write an elasticsearch query in C# which can search multiple words in multiple fields.  
For example.  
Query: John California Honda  
Fields: Name, State, Car  
This query should search the term John in all three fields and so on for the other terms present in the query.  
Note: the sequence can differ and the number of terms in the query can be more or less.

```
var searchResult= client.Search<cars>(s => s
          .AllTypes()
            .Size(50)
            .Query(q => q.Bool(b => b
               .Must(mu => mu
                           .MultiMatch(m => m
                                   .Fields(f => f.Field("Name").Field("State").Field("Car"))
                             .Query("John")
                              ) && q
                            .MultiMatch(m => m
                        .Fields(f => f.Field("Name").Field("State").Field("Car"))
                               .Query("Califronia")
                            ) 

```

Above is my code, How can I modify this query that it should match according to the number of terms in the query string. (Dynamic)

With [`multi_match` query](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-multi-match-query.html), the query input for each field will be analyzed using the analyzer configured for each field, so there should be no need to _tokenize_ the input yourself when constructing a query. For example

```auto
var searchResult = client.Search<cars>(s => s
    .AllTypes()
    .Size(50)
    .Query(q => q
        .MultiMatch(m => m
            .Fields(f => f
                .Field("Name")
                .Field("State")
                .Field("Car")
            )
            .Query("John California Honda")
        )
    )
);

```

is equivalent to

```auto
var searchResult = client.Search<cars>(s => s
    .AllTypes()
    .Size(50)
    .Query(q => q
        .DisMax(dm => dm
            .Queries(dq => dq
                .Match(m => m
                    .Field("Name")
                    .Query("John California Honda")
                ), dq => dq
                .Match(m => m
                    .Field("State")
                    .Query("John California Honda")
                ), dq => dq
                .Match(m => m
                    .Field("Car")
                    .Query("John California Honda")
                )
            )
        )

    )
);

```

where the query input to each `match` query will be analyzed using the analyzer configured for search for each of the `"Name"`, `"State"` and `"Car"` fields, respectively.

Thank you for taking the time to reply.  
Can you also guide me which analyzer works best with numeric fields?

You don't set an [analyzer](https://www.elastic.co/guide/en/elasticsearch/reference/current/analyzer.html) for numeric fields, only for `text` datatype fields.
