PHP搜索脚本增强功能

我有一个内置搜索功能的网站。它允许用户从主页面标题中搜索关键字。当用户搜索任何关键字时,结果始终为:

没有符合您查询的结果。

要查找任何项目,用户必须转到高级搜索选项并在搜索框中输入关键字,选中“搜索项目标题和说明”复选框,然后从下拉框中选择“两者” “列入”。

我无法弄清楚如何自动设置主页面搜索框来搜索每个选项。

以下是我搜索功能的代码。任何帮助都会非常感激:

<?php

session_start();

define ('IN_SITE', 1);

include_once ('includes/global.php');
include_once ('includes/class_formchecker.php');
include_once ('includes/class_custom_field.php');

include_once ('global_header.php');

$option = $db->rem_special_chars($_REQUEST['option']);
$option = (empty($option)) ? 'auction_search' : $option;
$template->set('option', $option);
$item_details = $db->rem_special_chars_array($_POST);
$template->set('item_details', $item_details);
$header_search_page = header5(GMSG_ADVANCED_SEARCH);
$template->set('header_search_page', $header_search_page);
if ($_REQUEST['search_empty'] == 1)
{
    $template->set('no_results_message', '<p align="center" class="errormessage">' . MSG_NO_RESULTS_QUERY . '</p>');
}
(string) $search_options_menu = null;
$search_options_menu .= display_link(process_link('search', array('option' => 'auction_search')), MSG_AUCTION_SEARCH, (($option = 'auction_search') ? false : true)) . ' | ';
$search_options_menu .= display_link(process_link('search', array('option' => 'seller_search')), MSG_SELLER_SEARCH, (($option = 'seller_search') ? false : true)) . ' | ';

        $template->set('custom_sections_table', $custom_sections_table);
        $tax = new tax();       
        $template->set('country_dropdown', $tax->countries_dropdown('country', $item_details['country'], null, '', true));
        //$template->set('state_box', $tax->states_box('state', $item_details['state'], $item_details['country']));
        break;
    case 'seller_search':
        $search_options_title = MSG_SELLER_SEARCH;

        break;
    case 'store_search':
        $search_options_title = MSG_STORE_SEARCH;
        break;

$template->set('search_options_title', $search_options_title);

进行研究后的这个问题是MySQL标准设置的结果。最小搜索长度必须大于3个字符。搜索长度为3个字符或更少时,不会产生任何搜索结果。
