Subject: Re: [htdig] Database Update

I tried the -a option but still no luck. It uses alternate files, so I can still use the search engine while htdig is indexing. But when htdig/htmerge is finished, my old database is wiped out so I loose all the data from prior searches.
I'm sure I am missing some option somewhere. Do most people re-index from scratch?

Run both htdig and htmerge with option -a
(= use alternate work file)
htdig/merge will then work on the file called s ...db.work
instead of the current .db files.
See htdig --help ;-)
Then copy the workfiles over the actual database.
( cd $DBDIR && test -f db.docdb.work &&
for f in *.work
# mv -f $f `basename $f .work`
# Keep alternate work files for next upgrade dig
cp -f $f `basename $f .work`
See the file "rundig" in the ht://dig bin dir for details.
Somewhere around line 40.
But as far as I remeber, htdig always does an update dig
unless you use -i
Try htdig -vv / htmerge -vv to see what is actually
Depending on the site you are digging, the following
might be helpful as well:
I have a server where all content is generated "on the fly"
from a database. So the document date is always "now"
causing htdig to retrieve the full site on every run.
No very nice since this is a big site, and I can't run the
dig via local filesystem naturally.
But this is actually not a ht://dig problem but lies with
the site's content. (And I haven't found a workaround
yet since the date of last document change is not even
in the database ;-( )
