Question

how to check my system sphinx version?

Answer 1

May be just run the command searchd without any parameter

It shows following when I just tried

Sphinx 0.9.9-release (r2117) Copyright (c) 2001-20009, Andrew Aksyonoff  .... 

Answer 2

Run searchd with '--help' parameter which show the searchd version:

searchd --help Sphinx 0.9.9-release (r2117) Copyright (c) 2001-2009, Andrew Aksyonoff
