# Ferret::Search::Spans::SpanFirstQuery

## Summary

A SpanFirstQuery restricts a query to search in the first `end` bytes of a field. This is useful since often the most important information in a document is at the start of the document.

## Example

To find all documents where "ferret" is within the first 100 characters (really bytes);

    query = SpanFirstQuery.new(SpanTermQuery.new(:content, "ferret"), 100)

## NOTE

SpanFirstQuery only works with other SpanQueries.

### Public Class Methods

new(span_query, end) → query click to toggle source

Create a new SpanFirstQuery which matches all documents where `span_query` matches before `end` where `end` is a byte-offset from the start of the field

    static VALUE
    frb_spanfq_init(VALUE self, VALUE rmatch, VALUE rend)
    {
        Query *q;
        Query *match;
        Data_Get_Struct(rmatch, Query, match);
        q = spanfq_new(match, FIX2INT(rend));
        Frt_Wrap_Struct(self, NULL, &frb_q_free, q);
        object_add(q, self);
        return self;
    }
