Why doesn't Sphinx search through indexed tables?

Question

Sphinx

I am adding a new indexing section. When indexing, the sphinx finds and inteks

indexing index 'blog'...
collected 25 docs, 0.2 MB
sorted 0.0 Mhits, 100.0% done
total 25 docs, 183834 bytes
total 0.008 sec, 20641589 bytes/sec, 2807.09 docs/sec

But it doesn't find it when searching.

protected $_searchSections = [
        'news',
        'blog',
        'publications',
        'seminars'
    ];
$request = $this->getRequest();
        $query = $request->getQuery('q');

        $page = $request->getQuery('p', 1);

        $adapter = $this->_getSearchPaginatorAdapter();

        $adapter->setQuery($query);
        $adapter->setPublishGroupIds($this->_getPublishGroupIds());
        $adapter->setSections($this->_searchSections);
        $adapter->setSortCallback(
            function ($e1, $e2) {
                return $e2->getPublishDate() - $e1->getPublishDate();
            }
        );

        $paginator = new Paginator($adapter);
