PHP and Manticore Search Development: Secrets to Improving Website Search Experience

As a modern website, providing an efficient and accurate search function is crucial to attracting users and improving user experience. The combination of PHP and Manticore Search can help us achieve this goal. This article will introduce how to use PHP and Manticore Search to develop a powerful search function and improve the search experience of the website.

1. Introduction to Manticore Search

Manticore Search is an open source full-text search engine based on the same code base of the Sphinx search engine. Manticore Search's powerful search capabilities and high-performance features make it the first choice for many websites and applications. It supports full-text search, real-time indexing, distributed search and other functions.

2. Install Manticore Search

First, we need to install Manticore Search on the server. You can download the installation package from the official website (https://manticoresearch.com/) and install it according to the relevant documents.

3. Set up the index

Before using Manticore Search, we need to create an index for our data. An index is a data structure used to store data and enable fast searching.

For example, we have a database of articles and we want to search on the title, content and tags. We can create an index called "articles" and specify the fields we need to search.

The following is a sample code to create an index:

<?php
// 连接到Manticore Search服务器
$mysqli = new mysqli('127.0.0.1', 'username', 'password', 'articles_db', 9306);

// 创建索引
$mysqli->query("DROP TABLE IF EXISTS articles_index");
$mysqli->query("CREATE TABLE articles_index(title TEXT, content TEXT, tags TEXT) 
    ENGINE = 'MANTICORE'");

// 将数据插入索引
$mysqli->query("INSERT INTO articles_index(title, content, tags) 
    VALUES('PHP开发入门指南', '本指南将介绍PHP开发的基础知识', 'PHP, 开发')");
$mysqli->query("INSERT INTO articles_index(title, content, tags) 
    VALUES('Manticore Search教程', '快速入门 Manticore Search', 'Manticore, 搜索引擎')");
...
?>

4. Perform search

After setting up the index, we can use PHP and Manticore Search to perform search operations.

The following is a sample code for a simple search function:

<?php
// 连接到Manticore Search服务器
$mysqli = new mysqli('127.0.0.1', 'username', 'password', 'articles_db', 9306);

// 执行搜索
$query = "SELECT * FROM articles_index WHERE MATCH('PHP开发')";
$result = $mysqli->query($query);

// 处理搜索结果
while ($row = $result->fetch_assoc()) {
    echo $row['title'] . "<br>";
    echo $row['content'] . "<br>";
    echo $row['tags'] . "<br>";
    echo "<br>";
}
?>

The above code will search for articles containing "PHP development" and output the title, content and tags.

5. Improve the search experience

In addition to the basic search functions, we can also improve the search experience through some techniques and optimization.

1. Use full-text search function

Manticore Search supports full-text search function, which can match and rank text. We can use the MATCH and AGAINST statements to perform full-text search operations.

For example, we can rank search results and sort them by relevance:

$query = "SELECT *, WEIGHT() AS relevance FROM articles_index WHERE MATCH('PHP开发') 
    ORDER BY relevance DESC";

2. Paging and sorting

For more search results In this case, we can use paging and sorting functions to manage the search results. You can use LIMIT and OFFSET statements to implement paging, and use the ORDER BY statement to implement sorting.

For example, we can display 10 results per page and control paging through LIMIT and OFFSET:

$query = "SELECT * FROM articles_index WHERE MATCH('PHP开发') 
    ORDER BY relevance DESC LIMIT 10 OFFSET 0";

3. Search suggestions

In order to improve the user experience , we can implement a search suggestion function to provide possible search keywords based on user input. This can be accomplished using Manticore Search's autocomplete feature.

$query = "CALL KEYWORDS('PHP开', 'articles_index', 10)";
$result = $mysqli->query($query);

while ($row = $result->fetch_assoc()) {
    echo $row['token'] . "<br>";
}

The above code will return relevant suggestions based on the keywords entered by the user.

6. Summary

By using PHP and Manticore Search, we can easily develop a powerful search function and improve the search experience of the website. We can use Manticore Search's full-text search, paging and sorting, search suggestions and other functions to achieve a more intelligent and efficient search. I hope this article can help you improve the search experience of your website and attract more users.
