     NAME
          indxbib - build inverted index for a bibliography

     SYNOPSIS
          indxbib database...

     DESCRIPTION
          indxbib makes an inverted index to the named databases (or
          files) for use by lookbib(1) and refer(1).  These files con-
          tain bibliographic references (or other kinds of informa-
          tion) 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 con-
          tinue until the next line starting with %.

          indxbib is a shell script that calls /usr/lib/refer/mkey and
          /usr/lib/refer/inv.  The first program, mkey, truncates
          words to 6 characters, and maps uppercase to lowercase.  It
          also discards words shorter than 3 characters, words among
          the 100 most common English words, and numbers (dates) <
          1900 or > 2000.  These parameters can be changed; see
          refer(1).  The second program, inv, creates an entry file
          (.ia), a posting file (.ib), and a tag file (.ic), all in
          the working directory.

     FILES
          /usr/ucb/indxbib
          x.ia, x.ib, x.ic, where x is the first argument, or if these
          are not present, then x.ig.

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

     BUGS
          Probably all dates should be indexed, since many disciplines
          refer to literature written in the 1800s or earlier.
