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

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

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);
