Magento – Changing advanced search results query – Magento 2

advanced-searchattributeslayered-navigationmagento2products

I've extended the default layered navigation in magento 2 so that filter parameters are added like so:

?free_from=304_303_302

Where option ids are separated by an underscore, in the above example the product list displays all products with one or more of the 3 options selected.

This allows users to add more that one filter in each filterable category.

My question is how do i extend the way the advanced search builds the advanced search results query, so that it matches the way the layered navigation applies filters.

Currently, when I select multiple options from the advanced search and select search, it adds the query parameters in the form of an array,

?free_from%5B%5D=303&free_from%5B%5D=304&free_from%5B%5D=302

I need to change this so that it matches the layered navigation query, can anyone help me on this?

I can see the action of the advanced form is returned from \Magento\CatalogSearch\Block\Advanced\Form getSearchPostUrl(), and that this then retrieved the url from Magento\Framework\View\Element\AbstractBlock getUrl($route = '', $params = []), which method should i override and how do i retrieve the params and define the structure of the query?

Any help on this would be greatly appreciated.

We studied such an option to allow multiple selection of filters while writing ElasticSuite.

The override should be in :

\Magento\CatalogSearch\Model\Layer\Filter\Attribute::_getItemsData() (URL Generation in which you should set value to the imploded value)
\Magento\CatalogSearch\Model\Layer\Filter\Attribute::apply (explode the value of the filter).

Then you need to fix the DI. Take cares it is located into the frontend area. You can read a full example here :

https://github.com/Smile-SA/elasticsuite/blob/master/src/module-elasticsuite-catalog/etc/frontend/di.xml

You may also encounter some SQL, SolR or ES problem to handle the array.

We have renounced to it since we do not use option ids but labels and it was a nightmare to handle multivalued this way. You can see the result here (looks likes your problem). : http://demo.magento-elastic-suite.io/index.php/women/tops-women.html?style_general%5B0%5D=Tee&style_general%5B1%5D=Pullover.

Hope it's help.

Magento – custom advanced search

You will need to extend few advance search classes.

First I believe you already familiar with magento module developing.

Now, you need to add this block file

class NameSpace_YourModule_Block_Search_Form extends Mage_CatalogSearch_Block_Advanced_Form
{

    /**
     * Retrieve collection of product searchable attributes
     *
     * @return Varien_Data_Collection_Db
     */
    public function getSearchableAttributes()
    {
        $attributes = $this->getModel()->getAttributes();
        return $attributes;
    }

    /**
     * Retrieve advanced search model object
     *
     * @return Mage_CatalogSearch_Model_Advanced
     */
    public function getModel()
    {
        return Mage::getSingleton('yourblock/block'); //this is your block name what you have declared in config.xml
    }
}

Now in your module

class NameSpace_YourModule_Block_Search_Form extends Mage_CatalogSearch_Model_Advanced
{
    /**
     * Retrieve array of attributes used in advanced search
     *
     * Filter for specific attributes only
     * @return array
     */
    public function getAttributes()
    {
        /* @var $allAttributes Mage_Catalog_Model_Resource_Eav_Resource_Product_Attribute_Collection */
        $allAttributes = $this->getData('attributes');
        if (is_null($allAttributes)) {
            $product = Mage::getModel('catalog/product');
            $allAttributes = Mage::getResourceModel('catalog/product_attribute_collection')
                ->addHasOptionsFilter()
                ->addDisplayInAdvancedSearchFilter()
                ->addStoreLabel(Mage::app()->getStore()->getId())
                ->setOrder('main_table.attribute_id', 'asc')
                ->load();

            $attributes = array();
            foreach ($allAttributes as $attribute) {
                if($attribute->getAttributeCode() == 'your_attribute_1' || $attribute->getAttributeCode() == 'your_attribute_2'){ //you can add as many as you want
                    $attributes[] = $attribute;
                }
            }
            foreach ($attributes as $attribute) {
                $attribute->setEntity($product->getResource());
            }
            $this->setData('attributes', $attributes);
        }
        return $attributes;
    }
}

Change your_attribute_1 and your_attribute_2 to your own attribute id.

Now, when you call $this->getSearchableAttributes() in your phtml file it will be showing only your own attributes.

Obviously you will need to create a controller to show your form and show the result too.

Your controller can have these codes only:

public function indexAction()
    {
        $this->loadLayout();
        $this->renderLayout();
        //Zend_Debug::dump($this->getLayout()->getUpdate()->getHandles());
    }

Remember you will also need layout file to render your index action.

Magento – Magento 2 Perform catalog search in the custom table

if you want to remove the dependency on Magento Fulltext catalog search then rewrite Magento/CatalogSearch/Model/Search/IndexBuilder.php file in your custom module and change SQL query(which will get data from your custom table) in function public function build (RequestInterface $request) then layer navigation filters also work properly.
