Platform is i86 Linux, kernel version 2.2.13. ht://Dig was built from
source with gcc 2.95.2 (or possibly egcs-2.91.66 -- don't remember
exactly when I upgraded the compiler).

Figuring that I was just failing to understand the online documentation
for url_part_aliases, I decided to dive into the code in order to get at
the definitive documentation =) From that, I could see quite clearly, I
think, the cause of the problem. Related to what you said above, I think
it all comes down to the fact that the merge doesn't do any encoding or
decoding related to url_part_aliases.
In database A, I have some URL's of the form...
which I need to "rewrite" as /newname/fileA
so I use something like /~name *1c in the dig config and /newname *1c in
the search config.
In database B, I have some URL's of the form...
When they are merged, they retain this form. But during the search, the
encode method of HtURLCodec tries to turn them into something like
*1c/fileB due to the url_part_aliases attribute in the search config.
And of course, dbf->Get() in DocumentDB fails because the document is
stored with .../newname/fileB as its key.
If I have this right, then I believe the last bit of the trick to get
things working the way I want is to run htdig on database A just as I
have been doing, but run htdig on database B using the url_part_aliases
settings in the search config file. Or maybe I am just deluding myself :)
Off to dig again.
