Complex Query with Sphinx

I am using Sphinx Search. It's working fine for me except one problem: I need to exclude some entries where a specific field doesn't contain a word.

Something that would look like this in MySQL:

SELECT * FROM table
   WHERE yescolumn = 'query' 
   AND othercolumn not like '%keyword%'

You can use Sphinx's extended query syntax to pick the fields you want to search. Try running a query through Sphinx like this:

@yescolumn query @othercolumn -keyword

So in a PHP page you might have a link to a Sphinx database named $sphinx:

$sphinx->SetMatchMode(SPH_MATCH_EXTENDED2);
$results = $sphinx->Query('@yescolumn query @othercolumn -keyword');
