HI

We are using ES through the .Net Nest [https://github.com/Mpdreamz/NEST](https://github.com/Mpdreamz/NEST)  
client.

The Index document indexed looks like this :

[ElasticType(  
Name = "tag",  
DateDetection = true,  
NumericDetection = true,  
SearchAnalyzer = "standard",  
IndexAnalyzer = "standard"  
)]  
public class TagIndexDto : AbstractIndexDto  
{

```
    [ElasticProperty(Index = FieldIndexOption.analyzed, OmitNorms = true)]
    public string Name { get; set; }
    [ElasticProperty(Index = FieldIndexOption.analyzed, OmitNorms = true)]
    public string Description { get; set; }
    [ElasticProperty(AddSortField = true)]
    public int FollowerCount { get; set; }
    [ElasticProperty(AddSortField = true)]
    public int ProductCount { get; set; }
    [ElasticProperty(AddSortField = true)]
    public int CatalogCount { get; set; }
}

```

What I want to do is to give a specific boost upon the values of the 3  
counts ( last 3 fields ). And the boost should be configurable , it means  
the exact value of the boost is not known at indexing time.  
Is that actually supported by lucene ? ES ? Or I am looking for a  
nonexisting feature ?

Thanks  
Roman
