I don't know--you could try to use the htdb_recover program in the 
htdb directory, but you might want to see below. BTW, if you've run 
htmerge at this point, you're unlikely to recover more information 
from them. The purpose of htmerge is to put the databases in a nice 
consistent state, so it most likely tried it's best to figure them 
out, then "cleaned them up."

Not necessarily. If you supply the -l flag to htdig, it will make 
sure the databases are consistent and write out a list of the URLs it 
still needs to index before exiting. Otherwise, the signal just kills 
it in the middle and there's no guarantee it wasn't in the middle of 
a write.
