PHP and Manticore Search Development: Building an Intelligent Search Recommendation Engine

In the Internet era, search engines are one of the main tools for us to obtain information. With the continuous development of search engines, users’ demands for the accuracy of search results and personalized recommendations are also increasing. In order to meet these needs, we can use PHP and Manticore Search, two powerful tools, to develop an intelligent search recommendation engine.

Manticore Search is a high-performance, full-text search engine developed based on Sphinx Search, which can efficiently process massive text data. As a popular server-side scripting language, PHP is easy to use and flexible, and is very suitable for developing search engines and recommendation systems.

Before we begin, we need to install Manticore Search. You can install it through source code compilation or using precompiled binaries. For specific steps, please refer to the official documentation of Manticore Search.

First, we need to create the Manticore Search configuration file, name it manticore.conf, and configure it accordingly. The configuration file can specify the index name, field name, index storage method, etc.

index search_engine {
    type = plain
    path = /var/www/search_engine/data/search_engine
    morphology = stem_en
    min_stemming_len = 4
    min_word_len = 1
    min_prefix_len = 2
    index_exact_words = 1
    blend_mode = phrase
    blend_chars = .,/-+_():;{}[]<>~`!@#$%^&*|"'=?``
    blend_short_words = 1
    blend_short_len = 2
    influx_throttle = threads=32
    dict = keywords_patch
}

Among them, index specifies the name of the index, type specifies the index storage method, and path specifies the storage path of the index file. Other configuration options can be adjusted based on specific needs.

Next, we can use PHP to connect and operate Manticore Search. First, we need to install the Manticore Search extension in PHP, which can be installed through PECL.

pecl install manticore

After the installation is complete, we can use the following code example to perform connection and search operations.

<?php
$manticore = new Manticore("localhost", 9306);
$manticore->connect();

$query = "SELECT * FROM search_engine WHERE MATCH('keyword')";
$result = $manticore->query($query);

if ($result !== false) {
    echo "Search result:
";
    while ($row = $result->fetch_assoc()) {
        echo "ID: " . $row['id'] . "
";
        echo "Title: " . $row['title'] . "
";
        echo "Content: " . $row['content'] . "
";
    }
} else {
    echo "Search failed.
";
}

$manticore->disconnect();
?>

In the above code, we first create a Manticore object and connect to Manticore Search through the connect() method. We can then execute our search query through the query() method. MATCH('keyword') in the query statement indicates the keyword to be searched.

If the search is successful, we can obtain the searched records by traversing the result set and output the corresponding content. Finally, we disconnect from Manticore Search through the disconnect() method.

In addition to basic search functions, Manticore Search also supports more complex query operations, such as fuzzy search, range search, sorting, etc. By flexibly using these functions, we can create a more intelligent and efficient search recommendation engine.

To sum up, using PHP and Manticore Search to develop an intelligent search recommendation engine is a very effective method. As a simple, easy-to-use and flexible language, PHP can help us quickly build web applications. As a high-performance full-text search engine, Manticore Search can meet users' needs for accuracy and personalized search results. By combining the advantages of both, we can create an intelligent search recommendation engine with powerful functions and excellent user experience.
