Custom search form not working

Hi!

I based my custom search form on the tutorial here: https://wpjobmanager.com/document/tutorial-creating-custom-job-search-form/

But its not filtering the jobs according to the keywords, its just displaying all jobs.

<form role="search" class="search-box" action="<?php bloginfo('url') ?>/jobs" id="" method="get">
                <label for="keywords">Keywords
                  <input type="text" name="search_keywords" value="" id="search_keywords" />
                </label>
                <label for="keywords">Location
                  <input type="text" name="search_location" id="search_location" />
                </label>

                  <input class="button large" type="submit" value="Search jobs" id="" />
            </form>

The URL I get after filling the form and clicking on Search is: https://localhost:8888/wordpress/jobs/?search_keywords=admin&search_location=singapore
