I want to get the search term of current user. And according to that search term get products using custom query.

My observer is calling only one time when Cache is enabled.

Please provide me some help or suggestion.

<event name="controller_action_postdispatch_catalogsearch_result_index">

 <observer name="searchObserver" instance="VendorModuleObserverSearchData" />

</event>


<?php

namespace VendorModuleObserverSearch;

use MagentoFrameworkEventObserver;
use MagentoFrameworkEventObserverInterface;
use MagentoFrameworkStdlibCookieCookieMetadataFactory;
use MagentoFrameworkStdlibCookieManagerInterface;

class Data implements ObserverInterface 

const COOKIE_NAME = 'categoryId';
const COOKIE_DURATION = 86400; // One day (86400 seconds)

protected $_cookieManager;

/**
 * @var CookieMetadataFactory
 */
protected $_cookieMetadataFactory;
protected $_queryFactory;
protected $_filterBuilder;
protected $_searchCriteriaBuilder;
protected $_searchInterface;

public function __construct(
CookieManagerInterface $cookieManager, CookieMetadataFactory $cookieMetadataFactory, MagentoSearchModelQueryFactory $queryFactory, MagentoFrameworkApiFilterBuilder $filterBuilder, MagentoFrameworkApiSearchSearchCriteriaBuilder $searchCriteriaBuilder, MagentoSearchApiSearchInterface $searchInterface
) 
 $this->_cookieManager = $cookieManager;
 $this->_cookieMetadataFactory = $cookieMetadataFactory;
 $this->_queryFactory = $queryFactory;
 $this->_filterBuilder = $filterBuilder;
 $this->_searchCriteriaBuilder = $searchCriteriaBuilder;
 $this->_searchInterface = $searchInterface;


/**

 * Below is the method that will fire whenever the event runs!

 *

 * @param Observer $observer

 */
public function execute(Observer $observer) 
 $data = $observer->getData();
 $searchTerm = $this->_queryFactory->get()->getQueryText();
 $this->_filterBuilder->setField('search_term')
 ->setValue($searchTerm)
 ->setConditionType("like");

 $this->_searchCriteriaBuilder->addFilter($this->_filterBuilder->create());
 $searchCriteria = $this->_searchCriteriaBuilder->create();
 $searchCriteria->setRequestName("quick_search_container");
 $searchResults = $this->_searchInterface->search($searchCriteria);

 print_r($searchResults->getItems());
 $products = $searchResults->getItems();
 foreach ($products as $product) 

 echo $id = $product->getId();
 $result[] = $id;

 
 exit;
 return $this;
