Do you think that underflow should map to the smallest representable number (like norm encoding does) or 0?
The bit vector will keep track of matches, so we don't need a non-zero score for that (and a field boost of 0 is valid anyway AFAIK), but on the other hand, higher level scoring routines sometimes filter out score==0. -Yonik Now hiring -- http://forms.cnet.com/slink?231706 --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
