I am happy to provide support via email and the google group - but please do not contact me on Skype or other instant messaging systems about Thinking Sphinx issues.
Further Documentation, Support and Discussion
There was once a PDF publication on Thinking Sphinx, published by Peepcode. Sadly, it’s no longer for sale (but it’s terribly out of date now anyway).
Keep in mind some of these posts may refer to features/code relevant to older versions of Thinking Sphinx.
