Sphinx PHP Product search and sorting optimization in e-commerce websites

In e-commerce websites, product search and sorting are important for user experience and sales conversion One of the factors. In order to improve the user's search experience and present results that best match user needs, Sphinx PHP is a very powerful and widely used full-text search engine. This article will introduce how to use Sphinx PHP to optimize product search and sorting on e-commerce websites, and provide specific code examples.

1. Install and configure Sphinx PHP

First, we need to install Sphinx PHP on the server of the e-commerce website. You can install it through the following command:

$ pecl install sphinx

After successful installation, you need to introduce Sphinx PHP into the configuration file of the website:

require_once 'sphinxapi.php';

2. Establish a product index

Before selecting products Before searching, you need to create a product index in Sphinx. First, create an index called "products". Assume that our product table is named "products", which contains fields such as id, name, description, price, etc. You can create an index through the following code:

$cl = new SphinxClient();
$cl->SetServer("localhost", 9312);
$cl->SetConnectTimeout(1);
$cl->SetArrayResult(true);

$cl->SetFieldWeights(array(
    'name' => 10,
    'description' => 5,
    'price' => 1
));

$cl->SetMatchMode(SPH_MATCH_ANY);
$cl->SetSortMode(SPH_SORT_RELEVANCE);

$cl->AddIndex('products');
$cl->AddQuery('iphone', 'products');

$result = $cl->RunQueries();

if ($result === false) {
    echo "搜索失败";
} else {
    foreach ($result['results'][0]['matches'] as $match) {
        echo "商品ID: " . $match['id'] . "<br>";
        echo "商品名称: " . $match['attrs']['name'] . "<br>";
        echo "商品描述: " . $match['attrs']['description'] . "<br>";
        echo "商品价格: " . $match['attrs']['price'] . "<br>";
        echo "<br>";
    }
}

The above code first creates a SphinxClient object and sets up a connection. Parameters, field weights, matching modes, and sorting modes. Then, the index name and table name to be searched are specified through the AddIndex() method, and the keywords to be searched are specified through the AddQuery() method. Finally, the search is performed through the RunQueries() method and matching product results are output.

3. Optimize product sorting

When searching for products, in addition to keyword matching, you also need to consider the issue of sorting. The following is an example that demonstrates how to sort based on product price:

$cl = new SphinxClient();
$cl->SetServer("localhost", 9312);
$cl->SetConnectTimeout(1);
$cl->SetArrayResult(true);

$cl->SetFieldWeights(array(
    'name' => 10,
    'description' => 5,
    'price' => 1
));

$cl->SetMatchMode(SPH_MATCH_ANY);
$cl->SetSortMode(SPH_SORT_EXTENDED, '@yesno ASC, price ASC');

$cl->AddIndex('products');
$cl->AddQuery('iphone', 'products');

$result = $cl->RunQueries();

if ($result === false) {
    echo "搜索失败";
} else {
    foreach ($result['results'][0]['matches'] as $match) {
        echo "商品ID: " . $match['id'] . "<br>";
        echo "商品名称: " . $match['attrs']['name'] . "<br>";
        echo "商品描述: " . $match['attrs']['description'] . "<br>";
        echo "商品价格: " . $match['attrs']['price'] . "<br>";
        echo "<br>";
    }
}

In the above code, the sorting mode is set to SPH_SORT_EXTENDED through the SetSortMode() method, and then specified through '@yesno ASC, price ASC' Sort by an additional field first (such as whether to stick or not) and then by price.

Summary:

Using Sphinx PHP to optimize product search and sorting on e-commerce websites can greatly improve the user's search experience and present results that best match user needs. This article introduces the installation and configuration methods of Sphinx PHP, as well as specific code examples on how to create product indexes and optimize product sorting. I hope this article will be helpful to developers who apply Sphinx PHP in e-commerce websites.
