You are right about adjacent hyphens maybe being not allowed, but that is a lack of information from the threads o/p. If he can better specify his needs i can construct better suited regexps. The point, though, was to show how a regexp can be constructed from a specification at all.

Description
The makes an inverted index to the named databases (or files) for use by and These files contain bibliographic 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 ``%''.
The command is a shell script that calls and The first program, truncates words to 6 characters, and maps upper case to lower case. 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. The second program, inv, creates an entry file (.ia), a posting file (.ib), and a tag file (.ic), all in the
working directory.
The command uses an inverted index made by to find sets of bibliographic references. It reads keywords typed after the ``>'' prompt on the
terminal, and retrieves records containing all these keywords. If nothing matches, nothing is returned except another ``>'' prompt.
It is possible to search multiple databases, as long as they have a common index made by In that case, only the first argument given to is
specified to
If does not find the index files (the .i[abc] files), it looks for a reference file with the same name as the argument, without the suf-
fixes. It creates a file with a '.ig' suffix, suitable for use with It then uses this fgrep file to find references. This method is sim-
pler to use, but the .ig file is slower to use than the .i[abc] files, and does not allow the use of multiple reference files.
