I posted this question a while ago.
I get these errors when trying to reindex the search DB, after moving from
the staging to the live server.
WordType::WordType: reading bad words from /var/www/html/htdig/bad_words
t, ignored because TOOSHORT
/usr/bin/rundig: line 81: 17797 Segmentation fault /usr/bin/htfuzzy
The thing is that I copied all the .conf files to the live server.
Are these settings not in the conf files?
