Yes, you'll need to change the db passwd in the one of the two locations & then you can run a cmd from your ssh terminal to force a new index & rotate them

Im assuming your using digitalpoints mod, so change the db passwd in sphinx.conf.ini

If u dont use digitalpoints mod, then you need to modify sphinx.conf

path to index as it will most likely differ on your system

cmds to run:

updatedb
locate indexer
/path/to/indexer --rotate --all

if that dont show updated threads/posts, do this below:
then HUP/restart searchd
