At the indexing stage, I'm thinking something along these lines:
my $r_tree_writer = KSx::RTree::RTreeWriter->new;
my $seg_writer = KinoSearch::Index::SegWriter->new;
my $invindexer = KinoSearch::InvIndexer->new(
invindex => MySchema->open('/path/to/invindex'),
seg_writer => $seg_writer,
RTreeWriter would need to implement add_doc(), add_segment(), and
finish(), plus possibly init().
Not that much to it! A lot of the work has already been done. We'll
have to make a bunch of classes public, e.g. SegInfo, InStream/
OutStream, but those are all reasonably mature by now.
