DESCRIPTIONSpan 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.

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.
