Creation of searchable mail-archive.
====================================

1)  Extract mails to external files, f.ex. one per month.

    Many mail-packages allows for automatic archiving to disk, but
    else it is simpel to do from MAIL. Example:

      $ MAIL
      MAIL> SELECT/FROM=FOOBAR-L/BEFORE=1-MAR/AFTER=1-FEB FOOBAR_1998_FEB.TXT
      MAIL> SELECT/FROM=FOOBAR-L/BEFORE=1-APR/AFTER=1-MAR FOOBAR_1998_MAR.TXT
      MAIL> SELECT/FROM=FOOBAR-L/BEFORE=1-MAY/AFTER=1-APR FOOBAR_1998_APR.TXT
      MAIL> EXIT

    Make sure, that the individual mails are seperated f.ex. with a
    form-feed (default for MAIL EXTRACT).

2)  Index the files with with one index per external file. That has
    two advantages:
      - you can build a new index relatively fast every time you add
        a new external file witout rebuilding everything
      - you can search one single month, one single year or
        everything

3)  Place MAILSEARCH.COM in you script-directory.

4)  Put MAP rules in the server config-file, so that the external
    files can be accessed.

5)  /htbin/mailsearch/<path>/<index> can now be used to search
    the archive.

Example:

Files are in DISK8:[FOOBAR]FOOBAR_<year>_<month>.TXT
Indexes are named FOOBAR_<year>_<month>
URL to access files are /archive/foobar/foobar_<year>_<month>.txt

The indexing commands will now be:

$ WWWINDEX DISK8:[FOOBAR]FOOBAR_<year>_<month>.TXT /MINIMUM=1 /NONUMBER -
   /OUTPUT=FOOBAR_<year>_<month> /TOPIC=(TEXT="SUBJECT: ",EXCLUDE) -
   /NOVERSION /FF

Now /htbin/mailsearch/archive/foobar/foobar_* will search the all
files, /htbin/mailsearch/archive/foobar/foobar_1998_* will search
the 1998 files and /htbin/mailsearch/archive/foobar/foobar_1998_apr
will search the 1998 april file.

Theese URL's can either be placed in a static HTML page or generated
dynamically by a script (a small COM-file calling F$SEARCH and
manipulation output a bit).
