Full text search in mongodb in Symfony 3.4 - mongodb

Question

I'm trying to use full text search in mongodb:
db.Product.createIndex({"name": "text"})
db.Product.find({$text: {$search: "xxxxx"}})
how to use this in controller to symfony?

Answer 1

First of all create Product entity(adjust to your needs)
<?php
/**
* #Document
* #Index(keys={"name"="text"})
*/
class Product
{
/** #Id */
public $id;
/** #Field(type="string") */
public $name;
/** #Field(type="float") */
public $price;
}
Look at $name and #Index annotation
Then use query builder text() method
// Run a text search against the index
$qb = $dm->createQueryBuilder('Product')
->text('words you are looking for');
More info you can find here
The other way is to create native query with expr() from doctrine query builder

Answer 2

Thank you for all the answers. In summary, the controller for the search engine looks like the following:
class SearchController extends Controller
{
public function searchBarAction()
{
$form = $this->createFormBuilder(null)
->setMethod('GET')
->add('search', TextType::class)
->getForm();
return $this->render('AppBundle:Components:_searchBar.html.twig', [
'form' => $form->createView()
]);
}
/**
* #param Request $request
*/
public function handleSearchAction(Request $request)
{
$searchData = $request->query->get('form')['search'];
$dbName = 'ece';
$connection = $this->container->get('doctrine_mongodb')->getConnection();
$mongo = $connection->getMongo();
$db = $mongo->selectDB($dbName);
$resultSetProduct = $db->Product->find([
'$text' => ['$search' => $searchData]
]);
$resultSet = $db->MainData->find([
'$text' => ['$search' => $searchData]
]);
$itemProduct = $resultSetProduct->count();
$itemSet = $resultSet->count() + $itemProduct;
return $this->render('search/index.html.twig', [
'searchData' => $searchData,
'resultSetProduct' => $resultSetProduct,
'itemProduct' => $itemProduct,
'itemSet' => $itemSet,
'resultSet' => $resultSet
]);
}
}
