How to set up phpcms unlimited model search

phpcmsv9 full site search, unlimited model, today I gained more knowledge. As we all know, phpcms searches based on models. After using this method, you can search the entire site

Simply modify the default search function of v9, and you can search the entire site content without modeling

The following is the index.php file in the modified search module

<?php
defined(&#39;IN_PHPCMS&#39;) or exit(&#39;No permission resources.&#39;);
pc_base::load_sys_class(&#39;form&#39;,&#39;&#39;,0);

  function __construct() {
    $this->db = pc_base::load_model(&#39;search_model&#39;);
    $this->content_db = pc_base::load_model(&#39;content_model&#39;);

Then add an "unlimited" to the header.html template (not here, just on other search box pages) For the search conditions, set the corresponding value of typeid to 0, and do the same processing for index.html and lists.html in the search, and the effect will be there. In this way, as long as the model is not selected, the search results will be the data that meets the conditions in all models.
