I am attempting to boost values for queries.

I'm searching across all fields and tables and returning 25 results for  
each type.

This is working fine however I need to Boost if the field name Name or the  
Field Name ID have the value in it.

I'm using ElasticSearchClient and sending this search.

search = new  
{

```
            query = new
            {
                query_string = new
                {
                    query = keyword,
                    default_field = "_all"
                }
            },
            from = 0,
            size = limitAllTypes,
            aggs = new
            {
                top_types = new
                {
                    terms = new
                    {
                        field = "_type"
                    },
                    aggs = new
                    {
                        top_type_hits = new
                        {
                            top_hits = new
                            {
                                size = limitPerType
                            }
                        }
                    }
                }
            }

```

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

How do i tell this to boost the name and id fields over all other fields.

If I'm searching for "My Searched Company" and that is in the Name field I  
want it at the top of the list. vs in notes, addresses or whatever other  
columns etc.

</div>

You could use a boosting query  
[http://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-boosting-query.html](http://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-boosting-query.html),  
or you could use a multi-match query  
[http://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-multi-match-query.html](http://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-multi-match-query.html) and  
add a boost directly to the name and id fields. Something like:

{  
"multi\_match": {  
"fields": [  
"name^2",  
"id^2",  
"\_all"  
],  
"query": keyword,  
"type": "best\_fields"  
}  
}

That tells Elasticsearch to search all fields, but to additionally search  
name and id and double their score if they match (that's the "^2" part).  
the "best\_fields" type will use the best score from the name, id, and \_all  
searches. You might want most\_fields to rank records that contain your  
query terms in name _and_ id _and_ other fields even higher. Note that my  
snippet is using the Query DSL. The syntax for the client you're using will  
probably be slightly different but that's the general idea.

Also note that I've been using Elasticsearch less than a year though so  
there may be better approaches, but that's where I'd start.

I was able to get this to work in ES using head and got back what i needed.

However translating to [ElasticSearch.net](http://ElasticSearch.net) has been an issue.

I have an anonymous type doing a match all query and this works fine and  
dandy.

I am trying to do the multi\_match as above but it isn't returning any  
results. I'm not sure

var myfields = "["Name^20","Id^20","\_all"]"; \<- this gets no  
results  
var myfields = "["Name^20","Id^20","\_all"]"; \<- this crashes with  
all kinds of errors

How do you do these bracketed values?

```
        var search = new
        {

            query = new
            {
                multi_match = new
                {
                    fields = myfields,
                    query = keyword,
                    type = "best_fields",
                    use_dis_max= "true"
                }
            },
            from = 0,
            size = limitAllTypes,
            aggs = new
            {
                top_types = new
                {
                    terms = new
                    {
                        field = "_type"
                    },
                    aggs = new
                    {
                        top_type_hits = new
                        {
                            top_hits = new
                            {
                                size = limitPerType
                            }
                        }
                    }
                }
            }
        };

I got it:

To add an array of var to an anonymous type add them like this.

```
        var field1 = new {field="Name^20"};
        var field2 = new {field = "_all"};
        var field3 = new {field = "Id^20"};
        var myfields = new [] {field1,field2};

```

This is slick now it puts the brackets in and there is no escaping 🙂
