Hi fellow Magento developers!

I'm currently trying to figure out how to use the FilterPool with classes instead of using it with the etc/di.xml.

It should be possible to use filters in a grid listing without setting up a di.xml virtual provider, however, I can't seem to work out how..

How I understand it now is like this:

You have a class, say Supplier, and you want it to be the DataProvider for given listing supplier_listing.xml, I also want to be able to apply Filter's to it, therefore i'm going to implement the interface FilterApplierInterface, which requires me to implement a method called apply().

However, the apply() method requires a Collection object and a Filter object, and this is where I get lost, how can I specify which data to apply and what Filter to use? Do I need to call the apply() method myself or should the Magento framework do this for me? If so, how can I tell Magento which Collection to use and what Filter to apply?

Any help would be appreciated, as I'm at a loss right now..

On a side note, i've used the di.xml virtual providers, however, I want to learn more about how Magento does it and how to do it yourself without the virtuals. Any help would be greatly appreciated!

Maybe not exact answer but it works.

Case though XML

There is an answer in magento2/module-cms.

Basically, there is responsible configuration for that:

<virtualType name="CmsGirdFilterPool" type="Magento\Framework\View\Element\UiComponent\DataProvider\FilterPool">
        <argument name="appliers" xsi:type="array">
            <item name="regular" xsi:type="object">Magento\Framework\View\Element\UiComponent\DataProvider\RegularFilter</item>
            <item name="fulltext" xsi:type="object">Magento\Framework\View\Element\UiComponent\DataProvider\FulltextFilter</item>

I didn't find a usage of CmsGirdFilterPool but you may try to use this example of Adminhtml Grid implementation.

Case thought PHP code

Also, I found out a simple non-XML way to use "fulltext" filter by customizing method \Magento\Ui\DataProvider\AbstractDataProvider::addFilter().

namespace Vendor\ModuleName\Ui\Component;

use Magento\Framework\Api\Filter;
use Magento\Framework\View\Element\UiComponent\DataProvider\FilterApplierInterface;
use Magento\Framework\View\Element\UiComponent\DataProvider\FulltextFilterFactory;
use Magento\Ui\DataProvider\AbstractDataProvider;

 * Class GridDataProvider
class GridDataProvider extends AbstractDataProvider
     * Fulltext filter
     * @var FilterApplierInterface
    protected $fulltextFilter;

     * Construct
     * @param string                $name
     * @param string                $primaryFieldName
     * @param string                $requestFieldName
     * @param object                $collectionFactory
     * @param FulltextFilterFactory $fulltextFilter
     * @param array                 $meta
     * @param array                 $data
    public function __construct(
        FulltextFilterFactory $fulltextFilter,
        array $meta = [],
        array $data = []
    ) {
        parent::__construct($name, $primaryFieldName, $requestFieldName, $meta, $data);
        $this->collection     = $collectionFactory->create();
        $this->fulltextFilter = $fulltextFilter->create();

     * Add processing fulltext query
     * Some workaround for fulltext search.
     * @param Filter $filter
     * @return void
    public function addFilter(Filter $filter)
        if ('fulltext' == $filter->getField()) {
            $this->fulltextFilter->apply($this->collection, $filter);
        } else {

     * Get data
     * @return array
    public function getData()
        $searchKey = $this->_request->getParam('search');
        if($searchKey) {
               return $this->getCollection()
                                        'filed-3'],OR More,
                                    ['like'=> '%'.$searchKey.'%'],
                                    ['like'=> '%'.$searchKey.'%'], 
                                    OR More values])
        } else {
              return $this->getCollection()
  • Thanks for your help, i`ve not been able to solve it yet, therefore, i'm still using the xml configurations to create the grids. But the addFilter() is something I didn't find yet, i'll definitely have a look at it!
