-;;; Commentary:
-
-;; The most recent version of this can always be fetched from the
-;; following FTP site:
-;; ls6-ftp.cs.uni-dortmund.de:/pub/src/emacs
-
-;; This code is still in the development stage but I'd like other
-;; people to have a look at it. Please do not hesitate to contact me
-;; with your ideas.
-
-;; What does it do? Well, it allows you to index your mail using some
-;; search engine (freeWAIS-sf and Glimpse are currently supported),
-;; then type `G G' in the Group buffer and issue a query to the search
-;; engine. You will then get a buffer which shows all articles
-;; matching the query, sorted by Retrieval Status Value (score).
-
-;; When looking at the retrieval result (in the Summary buffer) you
-;; can type `G T' (aka M-x gnus-summary-nnir-goto-thread RET) on an
-;; article. You will be teleported into the group this article came
-;; from, showing the thread this article is part of. (See below for
-;; restrictions.)
-
-;; The Lisp installation is simple: just put this file on your
-;; load-path, byte-compile it, and load it from ~/.gnus or something.
-;; This will install a new command `G G' in your Group buffer for
-;; searching your mail. Note that you also need to configure a number
-;; of variables, as described below.
-
-;; Restrictions:
-;;
-;; * Currently, this expects that you use nnml or another
-;; one-file-per-message backend.
-;; * It can only search one mail backend.
-;; * There are restrictions to the Glimpse setup.
-;; * There are restrictions to the Wais setup.
-;; * gnus-summary-nnir-goto-thread: Fetches whole group first, before
-;; limiting to the right articles. This is much too slow, of
-;; course. May issue a query for number of articles to fetch; you
-;; must accept the default of all articles at this point or things
-;; may break.
-
-;; The Lisp setup involves setting a few variables and setting up the
-;; search engine. The first variable to set is `nnir-mail-backend'.
-;; For me, `gnus-secondary-select-methods' contains just one select
-;; method, and this is also what I put in `nnir-mail-backend'. Type
-;; `C-h v nnir-mail-backend RET' for more information -- the variable
-;; documentation includes more details and a few examples. The second
-;; variable to set is `nnir-search-engine'. Choose one of the engines
-;; listed in `nnir-engines'. (Actually `nnir-engines' is an alist,
-;; type `C-h v nnir-engines RET' for more information; this includes
-;; examples for setting `nnir-search-engine', too.)
-
-;; You must also set up a search engine. I'll tell you about the two
-;; search engines currently supported:
-
-;; 1. freeWAIS-sf
-;;
-;; As always with freeWAIS-sf, you need a so-called `format file'. I
-;; use the following file:
-;;
-;; ,-----
-;; | # Kai's format file for freeWAIS-sf for indexing mails.
-;; | # Each mail is in a file, much like the MH format.
-;; |
-;; | # Document separator should never match -- each file is a document.
-;; | record-sep: /^@this regex should never match@$/
-;; |
-;; | # Searchable fields specification.
-;; |
-;; | region: /^[sS]ubject:/ /^[sS]ubject: */
-;; | subject "Subject header" stemming TEXT BOTH
-;; | end: /^[^ \t]/
-;; |
-;; | region: /^([tT][oO]|[cC][cC]):/ /^([tT][oO]|[cC][cC]): */
-;; | to "To and Cc headers" SOUNDEX BOTH
-;; | end: /^[^ \t]/
-;; |
-;; | region: /^[fF][rR][oO][mM]:/ /^[fF][rR][oO][mM]: */
-;; | from "From header" SOUNDEX BOTH
-;; | end: /^[^ \t]/
-;; |
-;; | region: /^$/
-;; | stemming TEXT GLOBAL
-;; | end: /^@this regex should never match@$/
-;; `-----
-;;
-;; 1998-07-22: waisindex would dump core on me for large articles with
-;; the above settings. I used /^$/ as the end regex for the global
-;; field. That seemed to work okay.
-
-;; There is a Perl module called `WAIS.pm' which is available from
-;; CPAN as well as ls6-ftp.cs.uni-dortmund.de:/pub/wais/Perl. This
-;; module comes with a nifty tool called `makedb', which I use for
-;; indexing. Here's my `makedb.conf':
-;;
-;; ,-----
-;; | # Config file for makedb
-;; |
-;; | # Global options
-;; | waisindex = /usr/local/bin/waisindex
-;; | wais_opt = -stem -t fields
-;; | # `-stem' option necessary when `stemming' is specified for the
-;; | # global field in the *.fmt file
-;; |
-;; | # Own variables
-;; | homedir = /home/kai
-;; |
-;; | # The mail database.
-;; | database = mail
-;; | files = `find $homedir/Mail -name \*[0-9] -print`
-;; | dbdir = $homedir/.wais
-;; | limit = 100
-;; `-----
-;;
-;; The Lisp setup involves the `nnir-wais-*' variables. The most
-;; difficult to understand variable is probably
-;; `nnir-wais-remove-prefix'. Here's what it does: the output of
-;; `waissearch' basically contains the file name and the (full)
-;; directory name. As Gnus works with group names rather than
-;; directory names, the directory name is transformed into a group
-;; name as follows: first, a prefix is removed from the (full)
-;; directory name, then all `/' are replaced with `.'. The variable
-;; `nnir-wais-remove-prefix' should contain a regex matching exactly
-;; this prefix. It defaults to `$HOME/Mail/' (note the trailing
-;; slash).
-
-;; 2. Glimpse
-;;
-;; The code expects you to have one Glimpse index which contains all
-;; your mail files. The Lisp setup involves setting the
-;; `nnir-glimpse-*' variables. The most difficult to understand
-;; variable is probably `nnir-glimpse-remove-prefix', it corresponds
-;; to `nnir-wais-remove-prefix', see above. The `nnir-glimpse-home'
-;; variable should be set to the value of the `-H' option which allows
-;; one to search this Glimpse index. I have indexed my whole home
-;; directory with Glimpse, so I assume a default of `$HOME'.
-
-;; 3. Namazu
-;;
-;; The Namazu backend requires you to have one directory containing all
-;; index files, this is controlled by the `nnir-namazu-index-directory'
-;; variable. To function the `nnir-namazu-remove-prefix' variable must
-;; also be correct, see the documentation for `nnir-wais-remove-prefix'
-;; above.
-;;
-;; It is particularly important not to pass any any switches to namazu
-;; that will change the output format. Good switches to use include
-;; `--sort', `--ascending', `--early' and `--late'. Refer to the Namazu
-;; documentation for further information on valid switches.
-;;
-;; To index my mail with the `mknmz' program I use the following
-;; configuration file:
-;;
-;; ,----
-;; | package conf; # Don't remove this line!
-;; |
-;; | # Paths which will not be indexed. Don't use `^' or `$' anchors.
-;; | $EXCLUDE_PATH = "spam|sent";
-;; |
-;; | # Header fields which should be searchable. case-insensitive
-;; | $REMAIN_HEADER = "from|date|message-id|subject";
-;; |
-;; | # Searchable fields. case-insensitive
-;; | $SEARCH_FIELD = "from|date|message-id|subject";
-;; |
-;; | # The max length of a word.
-;; | $WORD_LENG_MAX = 128;
-;; |
-;; | # The max length of a field.
-;; | $MAX_FIELD_LENGTH = 256;
-;; `----
-;;
-;; My mail is stored in the directories ~/Mail/mail/, ~/Mail/lists/ and
-;; ~/Mail/archive/, so to index them I go to the directory set in
-;; `nnir-namazu-index-directory' and issue the following command.
-;;
-;; mknmz --mailnews ~/Mail/archive/ ~/Mail/mail/ ~/Mail/lists/
-;;
-;; For maximum searching efficiency I have a cron job set to run this
-;; command every four hours.
-
-;; 3. Namazu
-;;
-;;
-
-;; Developer information:
-
-;; I have tried to make the code expandable. Basically, it is divided
-;; into two layers. The upper layer is somewhat like the `nnvirtual'
-;; or `nnkiboze' backends: given a specification of what articles to
-;; show from another backend, it creates a group containing exactly
-;; those articles. The lower layer issues a query to a search engine
-;; and produces such a specification of what articles to show from the
-;; other backend.
-
-;; The interface between the two layers consists of the single
-;; function `nnir-run-query', which just selects the appropriate
-;; function for the search engine one is using. The input to
-;; `nnir-run-query' is a string, representing the query as input by
-;; the user. The output of `nnir-run-query' is supposed to be a
-;; vector, each element of which should in turn be a three-element
-;; vector. The first element should be group name of the article, the
-;; second element should be the article number, and the third element
-;; should be the Retrieval Status Value (RSV) as returned from the
-;; search engine. An RSV is the score assigned to the document by the
-;; search engine. For Boolean search engines like Glimpse, the RSV is
-;; always 1000 (or 1 or 100, or whatever you like).
-
-;; The sorting order of the articles in the summary buffer created by
-;; nnir is based on the order of the articles in the above mentioned
-;; vector, so that's where you can do the sorting you'd like. Maybe
-;; it would be nice to have a way of displaying the search result
-;; sorted differently?
-
-;; So what do you need to do when you want to add another search
-;; engine? You write a function that executes the query. Temporary
-;; data from the search engine can be put in `nnir-tmp-buffer'. This
-;; function should return the list of articles as a vector, as
-;; described above. Then, you need to register this backend in
-;; `nnir-engines'. Then, users can choose the backend by setting
-;; `nnir-search-engine'.
-
-;; Todo, or future ideas:
-
-;; * Make it so that Glimpse can also be called without `-F'.
-;;
-;; * It should be possible to restrict search to certain groups.
-;;
-;; * There is currently no error checking.
-;;
-;; * The summary buffer display is currently really ugly, with all the
-;; added information in the subjects. How could I make this
-;; prettier?
-;;
-;; * A function which can be called from an nnir summary buffer which
-;; teleports you into the group the current article came from and
-;; shows you the whole thread this article is part of.
-;; Implementation suggestions?
-;; (1998-07-24: There is now a preliminary implementation, but
-;; it is much too slow and quite fragile.)
-;;
-;; * Support other mail backends. In particular, probably quite a few
-;; people use nnfolder. How would one go about searching nnfolders
-;; and producing the right data needed? The group name and the RSV
-;; are simple, but what about the article number?
-;;
-;; * Support compressed mail files. Probably, just stripping off the
-;; `.gz' or `.Z' file name extension is sufficient.
-;;
-;; * Support a find/grep combination.
-;;
-;; * At least for imap, the query is performed twice.
-;;
-;; * Support multiple mail backends. The information that is needed
-;; by nnir could be put in the server parameters. (Use sensible
-;; default values, though: include the name of the backend in the
-;; default value such that people do not have to mess with the
-;; server parameters if they don't want to.) It is not clear how to
-;; do the user interface, though. Hm. Maybe offer the user a
-;; completable list of backends to search? Or use the
-;; process-marked groups to find out which backends to search? Or
-;; always search all backends?
-;;
-
-;; Have you got other ideas?
