$query  = new  SolrQuery ( 'lucene' );

 $query
     -> setExpand ( true )
    -> setExpandRows ( 50 )
    -> setExpandQuery ( 'text:product' )
    -> addExpandFilterQuery ( 'manu:apple' )
    -> addExpandFilterQuery ( 'inStock:true' )
    -> addExpandSortField ( 'score' ,  SolrQuery :: ORDER_DESC )
    -> addExpandSortField ( 'title' ,  SolrQuery :: ORDER_ASC );
