Nope.

Well, document 44933532 isn't being found!

There's exactly one place than can produce that error message, and the
document id given is the one in the underlying database, not the docid
in the merged database.

It sounds like a consistency error in one of the databases.  If you can
keep everything else the same, but remove databases and see which is the
problem.  You can probably binary chop - so try:

DB=/closed20/closed21/closed22

If that works, hopefully the rest will fail:

DB=/closed23/closed24/closed25

Assuming one or the other fails, try each of the 3 in there individually
to see which is the problem.

Adding the extra term is presumably bringing the problem document into
the MSet - without b0026247 it will be hit 11 or lower.
