Generally, "empty key" errors are caused because you end up with an empty
database after htdig and htmerge have run. Most likely this is because
htdig didn't dig any documents containing indexable text it could hang on
to. Try running htdig -vvv (or even -vvvv for more verbose output), and
wade through the output to see where/why things are going wrong. See also

In this case it is at least getting some of your documents (hence no error),
but it's missing others. Same solution and FAQ entries as above apply.

Good question. There can be a number of reasons. The rundig script simply
calls htdig and htmerge, so you should be able to call these yourself. Note
that rundig also does two things you may not be doing from the command line.
1) it sets some environment variables, like TMPDIR, which may be needed to
get htdig, and especially htmerge, to run successfully. Without a TMPDIR
setting, it falls back to /tmp, which may not have enough free space
available for what these programs need. 2) It calls htdig and htmerge
using an explicit pathname (set in BINDIR in rundig), rather than relying
on a search of the PATH. If you have more that one version of htdig
installed, you may not be running the same version when you enter "htdig"
at the command line as you do when you run "rundig". Again, getting more
verbose output may help.
