WAISINDEX(1) USER COMMANDS WAISINDEX(1) NAME waisindex - Indexes files SYNOPSIS 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 | -nocon- tents ] 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. -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.

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 use- ful for databases with a large number of docu- ments, as the catalog contains 3 lines per docu- ment. -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 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. 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.

Brewster@think.com DIAGNOSTICS The diagnostics produced by the waisindex are meant to be self-explanatory. BUGS 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 data- bases 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.
