Combining Rescore Query with Highlight Query

[Saiprasad_Krishnamur (Saiprasad Krishnamurthy)]

I'm trying to apply Highlight Query and want to give more score to the number of fields highlighted by the highlight query than the term frequency on a field.

For example:
DOC 1:
{
"first_name": "John"
"last_name": "Smith"
"full_name": "John Smith"
}

DOC 2:    
{
"first_name": "John"
"last_name": "Stokes"      
"full_name": "John Smith John Smith"
    }

When I search using the full_name field, I want DOC1 should be the first match. This is my query.
