       lookall - look through all text files on UNIX

       lookall [ -Cn ]

       Lookall	accepts  keywords  from  the standard input, performs a search similar to that of
       refer(1), and writes the result on the standard output.	 Lookall  consults,  however,  an
       index to all the text files on the system rather than just bibliographies.  Only the first
       50 words of each file (roughly) were used to make the indexes.  Blank lines are	taken  as
       delimiters between queries.

       The -Cn option specifies a coordination level search: up to n keywords may be missing from
       the answers, and the answers are listed with those containing the most keywords first.

       The command sequence in /usr/dict/lookall/makindex regenerates the index.

       The directory /usr/dict/lookall contains the index files.

       `Warning: index precedes file ...'  means that a file has been changed since the index was
       made and it may be retrieved (or not retrieved) erroneously.

       Coordination  level  searching doesn't work as described: only those acceptable items with
       the smallest number of missing keywords are retreived.
