If you're using parse_doc.pl as an external parser for application/pdf files
(it uses pdftotext to convert the PDF files), you'll need to remove or
comment out this line (about line # 138):
s/[\-\255]/ /g; # replace hyphens with space
Then, as Geoff suggested, you'll need to set the allow_numbers and
extra_word_characters attributes in your htdig.conf file. You'll need to
reindex after that. The extra_word_characters attribute was introduced
Underscore characters shouldn't pose a problem in any case.
The hyphens within numbers could pose further problem for you if, in
the PDF files, there are line breaks at the hypens, like this: 078-
001. There's code in parse_doc.pl to dehyphenate words, but not to
rejoin hyphenated numbers. You'd need to modify the code to handle
these, if it turns out to be a problem for you. Of course, for numbers,
you'd need to keep the hyphen in when you rejoing them.
