magento2 - catalogsearch override template not working

Question

etc/frontend/routes:

<?xml version="1.0"?>
 <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">
<router id="standard">
    <route id="catalogsearch" frontName="catalogsearch">    
        <module name="Vendor_Module" before="Magento_CatalogSearch"/>
    </route>
</router>
</config>

Controller:

namespace Vendor\Module\Controller\Result;

use Magento\Framework\App\Action\Context;
use Magento\Catalog\Model\Session;
use Magento\Store\Model\StoreManagerInterface;
use Magento\Search\Model\QueryFactory;
use Magento\Catalog\Model\Layer\Resolver;


class Index extends \Magento\CatalogSearch\Controller\Result\Index
{
   protected $tglssearchHelper;
   protected $resultPageFactory;
   public function __construct(
    Context $context,
    \Magento\Framework\View\Result\PageFactory $resultPageFactory

) {
     parent::__construct($context);
     $this->resultPageFactory = $resultPageFactory;
}


public function execute()
{   //echo 'tag exe';die;
    $resultPage = $this->resultPageFactory->create();
    $resultPage->getLayout()->initMessages();
    $resultPage->getLayout()->getBlock('catalogsearch.leftnav');


    return $resultPage;
}

}

UPDATED view/frontend/layout: catalogsearch_result_index.xml

<referenceBlock name="catalogsearch.leftnav">
<action method="setTemplate">
    <argument name="template" xsi:type="string">Vendor_Module::layer/view.phtml</argument>
</action>
 </referenceBlock>

view/frontend/templates:
layer/view.phtml

/catalogsearch/result/?q=wirel... i get blank screen.

Answer 1

I think the problem is that the search form is not submitting to your controller. The URL it submits to is given by the getResultUrl method of Magento\Search\Helper\Data. You will need to override this method to make it return the address of your controller, 'catalogsearch/catalogsearch/resultcontroller', instead of 'catalogsearch/result'. This is assuming your module has this route defined in etc/frontend/routes.xml. Also, I think the controller needs to be named Index for get requests to work, so maybe use something like Tagalys\Tglssearch\Controller\Result\Index for your controller class and then register a route with name 'tglssearch' so that your endpoint is 'tglssearch/result'.

Try this

Custom_Search::form.mini.phtml
