Use PHP and Xunsearch to build an efficient procurement information search engine

With the rapid development of Internet technology, the amount and complexity of procurement information have also increased. In order to retrieve and display procurement information more efficiently, we can use PHP and Xunsearch to build an efficient procurement information search engine. This article will introduce how to use these two tools to quickly build and implement a powerful search function.

1. Installing and configuring Xunsearch

First, we need to install Xunsearch on the server. You can download the latest version of the installation package from the official website of Xunsearch and install it according to the official documentation. After the installation is complete, we need to configure Xunsearch.

In the Xunsearch installation directory, there is a directory named bin, which contains xunsearch.ini.php and xsctl.ini.php Two configuration files. We need to modify these two configuration files according to our own needs, such as setting the path of the data source, the path of the index file, and the relevant parameters of the search engine.

After the configuration is completed, we can manage and maintain the Xunsearch index through the xsctl command line tool. After running xsctl, you can enter some commands to operate the index, such as creating an index, adding documents, deleting documents, etc. For specific usage methods, please refer to Xunsearch’s official documentation.

2. Database design of procurement information search engine

Before using Xunsearch, we need to create a database and design a data table to store procurement information. Assume that our purchase information table is purchase_info, including the following fields: id, title, content, create_time etc. We can use SQL statements to create this table:

CREATE TABLE `purchase_info` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `title` varchar(255) NOT NULL,
  `content` text NOT NULL,
  `create_time` datetime NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

After creating the data table, we can insert the purchasing information into the database for subsequent search functions.

3. Integrate Xunsearch into the PHP project

First, we need to integrate Xunsearch into the PHP project. You can download the latest version of the PHP extension library from the official website of Xunsearch and install it according to the official documentation.

Using Xunsearch in PHP projects is very simple. First, we need to load Xunsearch’s extension library:

require_once '/path/to/XS.php';

Then, create an XS object through which various functions of Xunsearch can be used:

$xs = new XS('demo');

Among them, demo is the project name we specified in the Xunsearch configuration file.

4. Implementing the search function

In the PHP project, we can implement the search function through the following code:

$query = $_GET['q']; // 从请求参数中获取用户的搜索关键字

$xs = new XS('demo'); // 创建XS对象
$search = $xs->getSearch(); // 获取搜索对象

$search->setQuery($query); // 设置搜索关键字
$search->setLimit(10); // 设置返回结果的数量

$result = $search->search(); // 执行搜索

foreach ($result as $doc) {
    echo $doc->title . '<br>';
    echo $doc->content . '<br>';
    echo $doc->createTime . '<br>';
    echo '--------------------------<br>';
}

Through the above code, we first start from Obtain the user's search keywords from the request parameters, and then create an XS object and a search object. Next, we set the search keyword through the setQuery() method, and set the number of returned results through the setLimit() method.

Finally, perform the search operation and traverse the search results, outputting the title, content and creation time of the procurement information one by one.

5. Improve the search function

In order to further improve the accuracy of the search function, we can use Xunsearch's advanced search functions, such as query expansion, synonyms, fuzzy search, etc. You can refer to the official documentation of Xunsearch to learn more about the usage of advanced search.

In addition, we can also optimize the performance of the search function by adjusting the relevant parameters of the search engine. For example, you can improve the accuracy and relevance of search results by adjusting weights, setting field sorting rules, etc.

Summary:

This article introduces how to use PHP and Xunsearch to build an efficient procurement information search engine. Through reasonable database design and flexible use of Xunsearch, we can quickly build a powerful search engine, and optimize and improve the accuracy and efficiency of search through relevant search parameters and functions.

I hope this article can provide some help and guidance to developers who use PHP and Xunsearch to build search engines.

The code example is as above, I hope it will be helpful to you.
