;; Restrictions:
;;
-;; * If you don't use HyREX as your search engine, this expects that
-;; you use nnml or another one-file-per-message backend, because the
-;; others doesn't support nnfolder.
+;; * This expects that you use nnml or another one-file-per-message backend,
+;; because the others doesn't support nnfolder.
;; * It can only search the mail backend's which are supported by one
;; search engine, because of different query languages.
;; * There are restrictions to the Wais setup.
;; like this :
;; (setq gnus-secondary-select-methods '(
;; (nnimap "" (nnimap-address "localhost")
-;; (nnir-search-engine hyrex)
-;; (nnir-hyrex-additional-switches ("-d" "ddl-nnimap.xml"))
+;; (nnir-search-engine namazu)
;; )))
;; Or you can define the global ones. The variables set in the mailer-
;; definition will be used first.
;; For maximum searching efficiency I have a cron job set to run this
;; command every four hours.
-;; 3. HyREX
-;;
-;; The HyREX backend requires you to have one directory from where all
-;; your relative paths are to, if you use them. This directory must be
-;; set in the `nnir-hyrex-index-directory' variable, which defaults to
-;; your home directory. You must also pass the base, class and
-;; directory options or simply your dll to the `nnir-hyrex-programm' by
-;; setting the `nnir-hyrex-additional-switches' variable accordently.
-;; To function the `nnir-hyrex-remove-prefix' variable must also be
-;; correct, see the documentation for `nnir-wais-remove-prefix' above.
-
-;; 4. find-grep
+;; 3. find-grep
;;
;; The find-grep engine simply runs find(1) to locate eligible
;; articles and searches them with grep(1). This, of course, is much
;; are simple, but what about the article number?
;; - The article number is encoded in the `X-Gnus-Article-Number'
;; header of each mail.
-;; - The HyREX engine supports nnfolder.
;;
;; * Support compressed mail files. Probably, just stripping off the
;; `.gz' or `.Z' file name extension is sufficient.
