Sphinx. Filters doesn't work - sphinx

Question

I am try to configure Sphinx 2.1.6. When I enter word - I get some result, but when I don't do that or searching only with filters - I have error :
fullscan requires extern docinfo.
PHP:
require_once('/usr/share/sphinx/api/sphinxapi.php');//Include the Sphinx PHP API
$cl = new SphinxClient();//Start the SphinxClient class
$cl->SetMatchMode(SPH_MATCH_EXTENDED2);//Match all words or any word?
$cl->SetSortMode(SPH_SORT_RELEVANCE);//
$cl->setLimits(0,10);//Works like MySQL LIMIT
$searchWord = "*";
if(!empty($_POST['searchData'])) {
$searchWord = trim($_POST['searchData']);
}
// slider salary
//$firePHP -> log($boo);
if(!empty($_POST['min_salary'])){
$min_salary = (int)$_POST['min_salary'];
$max_salary = (int)$_POST['max_salary'];
$exclude = false;
$cl->SetFilterRange('salary', $min_salary, $max_salary, $exclude);
}
// filter select city []
if(!empty($_POST['cities'])) {
$city = $_POST['cities'];
$exclude = false;
$cl->SetFilter('city', $city, $exclude);
}
Sphinx config:
sql_query = \
SELECT id, occupation, experience, education, branch,
typeVacancy, salary, description, city, employer\
FROM vacancy_view
sql_attr_uint = salary
sql_attr_uint = city

You must have docinfo=inline configured on your index
http://sphinxsearch.com/docs/current.html#conf-docinfo
need docinfo=extern (which happens to be the default, so must of changed it!) for full-scans to work.
