The new bundled etcetera/sphinx-min.conf.dist andetc/example.sql analogy files tell you just that. Which means you work with the usual Perform Table query tocreate an RT index, next work with a few Input queries topopulate you to definitely directory having study, next a choose to search, andso for the.
