Building an e-book search tool based on PHP and coreseek
Introduction:
With the popularity of e-books and the rise of digital reading, online e-book resources are becoming more and more abundant. In order to facilitate readers to quickly find the e-books they need, it is necessary to build an efficient e-book search tool. This article will introduce how to use PHP and coreseek to build a simple e-book search tool, and provide corresponding code examples.
1. Preparation
Before starting, you need to make sure that PHP and coreseek have been installed.
2. Build a database
Before using coreseek to search, you first need to create a database and import the e-book data to be searched into it. Suppose we create a database named "books" and create a table named "book_list" in it to store e-book information.
The table structure is as follows:
CREATE TABLE book_list
(
id
int(11) NOT NULL AUTO_INCREMENT,
title
varchar(255) DEFAULT NULL,
author
varchar(255) DEFAULT NULL,
content
text,
PRIMARY KEY (id
)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
Insert the information of the e-book to be searched into the "book_list" table.
3. Install and configure coreseek
source book_source
{
type = mysql sql_host = localhost sql_user = root sql_pass = password sql_db = books sql_port = 3306 sql_sock = /var/run/mysqld/mysqld.sock sql_query_pre = SET NAMES utf8 sql_query = SELECT id, title, author, content FROM book_list
}
indexer
{
mem_limit = 128M
}
searchd
{
listen = 127.0.0.1:9312:mysql41 log = /path/to/log/searchd.log query_log = /path/to/log/query.log read_timeout = 5 max_children = 30 pid_file = /path/to/log/searchd.pid max_matches = 1000 seamless_rotate = 1 preopen_indexes = 0 unlink_old = 1
}
The "sql_host", "sql_user", "sql_pass", "sql_db" and other parameters in the configuration file need to be modified according to the actual situation.
4. PHP code example
The following is a simple PHP code example for implementing the e-book search function:
2d55ba558b275c1ecf451c3b473c316fSetServer("localhost", 9312);
$cl->SetMatchMode(SPH_MATCH_EXTENDED2);
$cl->SetSortMode(SPH_SORT_RELEVANCE);
$result = $cl->Query($keyword, "book_index");
if ($result["total"] > 0) {
echo "共找到" . $result["total"] . "本书"; echo "<ul>"; foreach ($result["matches"] as $match) { // 根据书籍ID从数据库中获取书籍信息并显示 $book = get_book_info($match["id"]); echo "<li>" . $book["title"] . ", 作者:" . $book["author"] . "</li>"; } echo "</ul>";
} else {
echo "未找到相关书籍";
}
function get_book_info($id) {
// 从数据库中根据书籍ID查询并返回书籍信息
}
?>
In the above code, first initialize and set relevant parameters through the SphinxClient class. Then call the Query method to search and display the search results accordingly.
It should be noted that the logic of obtaining book information from the database according to the book ID needs to be written according to the actual situation.
Summary:
This article introduces how to use PHP and coreseek to build an e-book search tool based on Chinese full-text retrieval, including the installation and configuration of coreseek and PHP code examples to implement the search function. Through this search tool, readers can quickly find the e-books they need and improve reading efficiency. Of course, this is just a simple example, and more complex function expansion and optimization can be carried out according to actual needs.
