Sphinx. A lot of queries. PHP API

Hello.
With the Sphinx is familiar enough.
I have 5 pages. One need to look at the entire database.
This made the trail. configuration file: pastebin.org/331010
Now I have to search through the database where postid = the specific value to something
to enter in the config even necessary?
And what to write in the PHP file to output another search, not
the entire base?
I hope it is clear explained :) Thank you
