Sorry for the slow response, I was camping...

If you're only using one notmuch index, it's enough to set the global
options like `gnus-search-notmuch-remove-prefix'. If you've got two
nnmaildir servers each with its own notmuch index, you'll have to
specific the different prefixes within the engine configuration:

((nnmaildir "One"
   (directory "~/Mail/one/"
     (gnus-search-engine gnus-search-notmuch
       (remove-prefix "~/Mail/one/"))))
 (nnmaildir "Two"
   (directory "~/Mail/two/"
     (gnus-search-engine gnus-search-notmuch
       (remove-prefix "~/Mail/two/")))))

Note how the sexps are nested, it's important that the engine-related
variables go within the engine configuration sexp.

I realize that 'remove-prefix is redundant with the nnmaildir 'directory
setting here, and hope to eventually be able to get rid of that.

Hope that helps,
Eric
