       waisindex - Indexes files

       waisindex [ -d index_filename ] [ -a ] [ -r ] [ -mem mbytes ]
       [ -register ] [ -export ] [ -e [ file ] ] [ -l log_level ]
       [ -pos | -nopos ] [ -nopairs | -pairs ] [ -nocat ] [ -T type ]
       [ -t type ] [ -contents | -nocontents ] filename filename ...

       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.

       -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 system of the
                 machine running waisindex.  It works over NFS, but it is much

       -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

       -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 databases, 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.

       -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 connection information, and is expected
                 to be used only for local searches.

       -e [ filename ]
                 Redirect error output to pathname, if supplied, or to
                 /dev/null.  Error output defaults to stderr, unless -s is
                 selected, in which case it defaults to /dev/null.

       -l log_level
                 set logging level.  Currently only levels 0, 1, 5 and 10 are
                 meaningful: Level 0 means log nothing (silent).  Level 1 logs
                 only errors and warnings (messages of HIGH priority), level 5
                 logs messages of MEDIUM priority (like indexing filename
                 info).  Level 10 logs everything.

       -pos (-nopos)
                 Include (don't include - default) word position information
                 in the index.  This will increase the index size, but will
                 allow search engines to do proximity.

       -nopairs (-pairs)
                 Don't build (build - the default) word pairs from consecutive
                 capitalized words.

       -nocat    Inhibits the creation of a catalog.  This is useful for
                 databases with a large number of documents, as the catalog
                 contains 3 lines per document.

       -contents (-nocontents)
                 Include (exclude) the contents of the file from the index.
                 The filename and header will still be indexed.  Default is
                 type depedant.

       -T type   Sets the TYPE of the document to "type".

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

       filename filename...
                 These are the files that will be indexed according to the
                 arguments above.  To insure the files are registered in the
                 filename table correctly, it is advised that these be full
                 paths (beginning with a /).  If the database is to be used
                 from a machine other than the machine on which the index is
                 created, this should be a machine-independant path.

       The diagnostics produced by the waisindex are meant to be self-

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

       Due to some compile time constants the document table is limited to 16
       Megabytes.  This limits the indexer to databases with headlines that
       add up to less than 16 megabytes (since thats the principal component
       of the table).  This is typically a problem for database types where a
       record is essentially a headline (one_line, archie).

       See the note in ir/README in the wais distribution for more detail.
