As of the most recent commit, goiardi can now rebuild its search index in case it accidentally got deleted or corrupted somehow.

To rebuild, just run knife index rebuild (or knife index rebuild -y if you don’t want to be bothered to press “y” to confirm that you really want to do it). You’ll get a message from knife that ‘knife index rebuild’ has been removed for Chef 11+ servers. This can be ignored; while goiardi identifies itself as a Chef 11+ server, this command will work because they’ve kept it in for older versions of Chef.
