sphinx + php. Why is the Weight in the response calculated incorrectly?

Question

PHP

Sphinx is installed and more or less configured. When executed, displays the correct answers, and specifies the weight and sorts by it. Downloaded, configured the library to work with php. Connection and call code:
seacrh "проект"

$this->_cl = new \SphinxClient();
        $this->_cl->SetServer( "localhost", 9312 ); 
        $this->_cl->SetConnectTimeout( 1 ); 
        $this->_cl->SetMaxQueryTime(1000);
        $this->_cl->SetRankingMode( SPH_RANK_BM25 ) ;
        $this->_cl->SetMatchMode( SPH_MATCH_ALL  ); 
        $this->_cl->SetSortMode( SPH_SORT_RELEVANCE ) ;

        $result = $this->_cl->Query( $this->_q, $this->_indexName );

No errors - number of matches, list of words, etc. everything is right. BUT the weight of all results = 1. Ie. always the same and sorting does not occur.
Tried to change SetRankingMode - to no avail. What could be causing this behavior and how to overcome it.
Thanks

$this->_cl = new \SphinxClient();
        $this->_cl->SetServer( "localhost", 9312 );
        $this->_cl->SetConnectTimeout( 1 ); 
        $this->_cl->SetMaxQueryTime(1000); 

        $this->_cl->SetMatchMode( SPH_MATCH_EXTENDED  );     // <--------
        $this->_cl->SetSortMode( SPH_SORT_RELEVANCE ) ;
        $result = $this->_cl->Query( $this->_q, $this->_indexName );

you need to fight the library, of course,
try to expose this trinity

$this->_cl->SetRankingMode( SPH_RANK_BM25 ) ;
 $this->_cl->SetMatchMode( SPH_MATCH_ALL  ); 
 $this->_cl->SetSortMode( SPH_SORT_RELEVANCE ) ;

in the same modes as on the naked sphinx
