bug#73581: 29.4; Gnus: Error doing a search on nnmaildir with gnus-search-find-grep

[Daniel Cerqueira]

I am coming back to this issue.  It still is unresolved.

I have made some progress, but still I get an error.  Here is what I
have done:


My search configuration:

(setq gnus-search-default-engines
      '((nnimap . gnus-search-imap)
        ;; (nnmaildir . gnus-search-find-grep)
        ;; (nnselect . gnus-search-nnselect)
        (nnselect . gnus-search-find-grep)))

(setq gnus-select-method
      `(nnmaildir "email"
                  (directory ,(expand-file-name "~/Mail"))
                  (remove-prefix ,(expand-file-name "~/Mail"))
                  (nnmaildir-directory ,(expand-file-name "~/Mail"))
                  (gnus-search-engine gnus-search-find-grep)))


My error message:

nnselect-generate-artlist: gnus-search-run-query on ((search-query-spec (query 
. parabéns) (raw)) (search-group-spec (nnmaildir:email friends))) gave error 
(wrong-type-argument stringp nil)
nnselect-generate-artlist: nil on nil gave error (void-function nil) [2 times]
