=== Span First Query

Matches spans near the beginning of a field. The span first query maps
to Lucene `SpanFirstQuery`. Here is an example:

[source,js]
--------------------------------------------------
{
    "span_first" : {
        "match" : {
            "span_term" : { "user" : "kimchy" }
        },
        "end" : 3
    }
}    
--------------------------------------------------

The `match` clause can be any other span type query. The `end` controls
the maximum end position permitted in a match.
