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.
