Xapian discuss - Aug 2007 - Boolean merging of DB's

Hi,

I'm wondering if there is a xapian-compact tool that lets me do boolean
merging
of  2 xapian db's into one db.

Take this scenario: I have db 'A' with 100 doc's and db 'B'
with 30 doc's. Most
of the docs in B will also be in A, but with newer content, so when I merge
them, I want to make a db 'C' with everything in A, but anything newer
that's
contained in B will overwrite any A entries.

Makes sense?

Actually, please ignore me, this doesn't quite make sense. There's no
way to
know the mapping of a document in one db to the "same" document in
another db...

It's all good, I can make a custom merge app that can do this...
