magento2 custom observer not getting called with execute()

Question

is there any need to override my custom observer.

I have an observer like:

\Vendor\Module\Observer\MyObserver.php

<?php
 namespace Vendor\Module\Observer;
 use \Magento\Framework\Event\Observer;
 use Magento\Framework\Event\ObserverInterface;
 class MyObserver implements ObserverInterface
 {
/**
 * @var \Vendor\Module\Model\EngineFactory
 */
protected $tglssearchEngineFactory;
public function __construct(
 \Vendor\Module\Model\Engine $tglssearchEngineFactory
) {
 $this->tglssearchEngineFactory = $tglssearchEngineFactory;
}
 /* public function createSearchObject(\Magento\Framework\Event\Observer $observer)
{
 echo 'obssr';
 $this->tglssearchEngineFactory->create()->getCatalogResult();
} 
*/
 public function execute(\Magento\Framework\Event\Observer $observer)
 {
 echo 'obssrexe';
 $event = $observer->getEvent();
 $this->tglssearchEngineFactory->create()->getCatlogSearchResult();
}
 }

etc/frontend/events.xml

<?xml version="1.0"?>
 <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
 <event name="controller_action_predispatch_catalogsearch_result_index">
 <observer name="controller_action_predispatch_catalogsearch_result_handler" instance="vendor\Module\Observer\MyObserver"/> 
</event>
</config>

Is my event name correct?

My router frontname: tgllsearch

Controller name: result

Action: index

Now in my home page, when i try to search for a keyword for a product, the url gets redirected to

http://localhost:1338/magento2x_2/catalogsearch/result/?q=wirel

which i want it as

http://localhost:1338/magento2x_2/tgllsearch/result/?q=wirel

But from : catalogsearch/result/?q=wirel my echo obssrexe is printing.

Should i have to override my Observer

Answer 1

I think you need to rewrite controller of Magento_CatalogSearch and not the Observer.
