For example:
$builder = $this->modelsManager->createBuilder()
->from('\Core\Model\LanguageTranslation')
->where("\\Core\\Model\\LanguageTranslation.original LIKE '%{$search}%'")
->orWhere("\\Core\\Model\\LanguageTranslation.translated LIKE '%{$search}%'");
Too long... Is there some possibility to add alias for table?
