Yii2 + Sphinx: How to solve Undefined index: Index error?

Question

Sphinx

I use https://github.com/yiisoft/yii2-sphinx
specified in the configuration file
'sphinx' => [
'class' => 'yii\sphinx\Connection',
'dsn' => 'mysql:host=localhost;port =9306;dbname=test',
'username' => 'root',
'password' => 'root',
],
in the controller:
static public function search()
{
return Test::find()
->from(self ::tableName())
->andWhere(['price' => 500])
->all();
}
As a result I get Undefined index: Index

Answer 1

1) check if sphinx is running ps aux | grep searchd
2) run sudo service sphinxsearch restart
2) it is important to specify 127.0.0.1 in the config and not localhost

Answer 2

what's in the sphinx config?
