The goal is to optimize the pagerank calculating algorithm so can have continuous updates (10000 blogs at a time 24/7) but more likely we'll end up refreshing the index once a weeks or so (hopefully each night). > > > You might also be able to keep the rank info in a flat file via the > ExternalFileField and the FileFloatSource and do FunctionQuery stuff that > way.

Depends on how that field get's re-read/indexed I guess. Or is it used at query time solely ? I feel that googling ExternalFileField does not really give the "meat" I need to narrow this down.
