The "How it works" page in the ht://dig documentation says, "if you want to
only update changed documents, these changes have to be merged into the
searchable database." I'm not clear on how that is accomplished. Do I use
the config file to limit digging to directories that I know have been
updated?
I have been running htdig with the -a option to use alternate work files.
I found that new digs and merges didn't update the databases that htsearch
was using. In other words, I had a folder full of 'db.docdb',
'db.wordlist', etc. as well as 'db.docdb.work', 'db.wordlist.work', etc.
Only the '.work' files were being updated. So I have been using the
following 'rundig' script:
#! /bin/sh
/home/httpd/htdig/bin/htdig -v -a -s -t
/home/httpd/htdig/bin/htmerge -v -a -s
mv /home/httpd/htdig/db/db.wordlist.work \
/home/httpd/htdig/db/db.wordlist
mv /home/httpd/htdig/db/db.words.db.work \
/home/httpd/htdig/db/db.words.db
mv /home/httpd/htdig/db/db.docs.index.work \
/home/httpd/htdig/db/db.docs.index
mv /home/httpd/htdig/db/db.docdb.work \
/home/httpd/htdig/db/db.docdb
The result is to do a completely new dig and merge within the '.work' files
and then use them to overwrite the old database. My impression from the
documentation is that there is a better way to do updates. Any suggestions
on how to use my work files?
