NAME
     waisindex - Indexes files

SYNOPSIS
     waisindex [ -d index_filename ] [ -a ] [ -r ]
     [ -mem mbytes ] [ -register ] [ -t type ] [ -export ]
     filename filename ...

DESCRIPTION
     waisindex creates an index of the words in files so that
     they can be searched quickly (see waissearch).  The index
     takes about as much disk space as the original text.  It
     also creates a new source structure named index_filename.src
     if none exists.

OPTIONS
     -d index_filename
               This is the base filename for the index files.
               Therefore if /usr/local/foo is specified, then the
               index files will be called /usr/local/foo.dct etc.
               The index should be stored on the local file sys-
               tem of the machine running waisindex.  It works
               over NFS, but it is much slower.

     -a        Append this index to an existing one.  Useful for
               incremental additions or updates.  This will only
               add onto an index, so that if a file has changed,
               it will get reindexed, but the old entries will
               not be purged.  Therefore, to save space, it is a
               good idea to reindex the whole set of files
               periodically.

     -r        Recursively index subdirectories.

     -mem      How much main memory to use during indexing.  This
               variable will have a large effect on how fast
               indexing is done.

     -register Register this database with the directory of
               servers.  You are encouraged to register data-
               bases, but only ones that will be consistently
               running.  The directory of servers is available to
               anyone that is on the internet or can phone in.

     -t type   This is the format of files that are handled by
               waisindex.  It is easy to parse a different for-
               mat, but that has to be done by changing the
               source (ircfiles.c).  To find out the list of
               currently known types, execute the waisindex com-
               mand with no arguments and it will list them.

     -export   This causes the resulting source description file
               to include the host-name and tcp-port for use by
               the clients.  Otherwise the file contains no con-
               nection information, and is expected to be used
               only for local searches.

DIAGNOSTICS
     The diagnostics produced by the waisindex is meant to be
     self-explanatory.


BUGS
     It temporarily takes twice the space it needs for an index.
