On a percolate request, can the doc be returned with the matched words  
highlighted? I tried doing this by specifying highlight settings when I  
registered the percolator (using NEST in C#)

private bool RegisterPercolator(string name, string query)  
{  
var c = this.ConnectedClient;  
var r = c.RegisterPercolator(  
FilterName,  
name,  
String.Format(  
@"{{  
""query"" : {{  
""query\_string"" : {{  
""query"" : ""{0}""  
}}  
}},  
""highlight"" : {{  
""fields"" : {{  
""some\_field"" : {{}}  
}}  
}}  
}}", query)  
);  
return (r.IsValid && r.OK);  
}

I then percolate a document which correctly returns the match, but no  
additional highlight information:

{  
"ok" : true,  
"\_index" : "\_percolator",  
"\_type" : "index\_name",  
"\_id" : "xxxx",  
"\_version" : 1  
}

Is there anyway to use the highlight feature with the percolator?

No, its only a match/no match thing.
