By manually deleting some files in the datastore dir, you have left it
in an inconsistent state. Queries are executed against the index and
the presence of the data file in itself doesn't affect what you see in
the list view.

Perhaps the files you deleted weren't that big? 'du -s datastore/* |
sort -n | tail' may be helpful here.

Yes, this is planned, though don't know when will be finally done.

Also plan to improve this, but I'm not sure if will be doable for the
next release, though scripts for inspecting the contents of the
datastore could be done very easily with some knowledge of python.
I'll be happy to give pointers if someone wants to spend some time on
this.

Check out the copy-from-journal command, should make this much easier.
