NAME

       Lucy::Search::Span - An offset, a length, and a weight.

SYNOPSIS

           my $combined_length = $upper_span->get_length
               + ( $upper_span->get_offset - $lower_span->get_offset );
           my $combined_span = Lucy::Search::Span->new(
               offset => $lower_span->get_offset,
               length => $combined_length,
           );
           ...

DESCRIPTION

       Span objects store information about a span across an array of...  something. The unit is
       context-dependent.

       Text is one possibility, in which case offset and length might be measured in Unicode code
       points.  However, the Span could also refer to a span within an array of tokens, for
       example -- in which case the start and offset might be measured in token positions.

CONSTRUCTORS

   new( [labeled params] )
           my $span = Lucy::Search::Span->new(
               offset => 75,     # required
               length => 7,      # required
               weight => 1.0,    # default 0.0
           );

       •   offset - Integer offset, unit is context-dependent.

       •   length - Integer length, unit is context-dependent.

       •   weight - A floating point weight.
