NAME
     indxbib - create an inverted index to a bibliographic  data-
     base

SYNOPSIS
     /usr/ucb/indxbib database-file...

DESCRIPTION
     indxbib makes an inverted index to the  named  database-file
     (which  must reside within the current directory), typically
     for use by lookbib and refer.  A database  contains  biblio-
     graphic references (or other kinds of information) separated
     by blank lines.  A  bibliographic  reference  is  a  set  of
     lines,  constituting  fields  of  bibliographic information.
     Each field starts on a line beginning with a  `%',  followed
     by  a  key-letter, then a blank, and finally the contents of
     the field, which may continue until the next  line  starting
     with `%' (see addbib).  indxbib is a shell script that calls
     two programs:  mkey and inv.   mkey  truncates  words  to  6
     characters, and maps upper case to lower case.  It also dis-
     cards words shorter than 3 characters, words among  the  100
     most  common  English words, and numbers (dates) < 1900 or >
     2000. These parameters can be changed.  indxbib  creates  an
     entry  file (with a .ia suffix), a posting file (.ib), and a
     tag file (.ic), in the working directory.

FILES
     /usr/ucblib/reftools/mkey
     /usr/ucblib/reftools/inv
     *.ia                entry file
     *.ib                posting file
     *.ic                tag file
     *.ig                reference file

SEE ALSO
     addbib(1), lookbib(1), refer(1), roffbib(1), sortbib(1).

NOTES
     All dates should probably be indexed, since many disciplines
     refer  to literature written in the 1800s or earlier.  indx-
     bib does not recognize pathnames.
