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.
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.
