PHP and Manticore Search development: Create a unique search result display

Overview:
In the modern Internet era, search engines have undoubtedly become one of the preferred tools for users to obtain information. And for website and app developers, providing efficient, accurate, and unique presentation of search results is key. This article will introduce how to use PHP and Manticore Search to develop and optimize search result display.

Manticore Search Introduction:
Manticore Search is a full-text search service developed based on the open source search engine Sphinx. It provides high performance, scalability and comprehensive search capabilities. It is very convenient to use PHP to connect and query the Manticore Search service, allowing us to obtain accurate result data based on search keywords.

1. Install and configure Manticore Search:
   First, we need to install and configure Manticore Search. Manticore Search can be downloaded and installed from the official website (https://manticoresearch.com/). After successful installation, we need to perform basic configuration, including index definition, search service configuration, etc. For specific configuration details, please refer to the Manticore Search official documentation.
2. Connecting to the Manticore Search service:
   In PHP, we can use the official extension "manticore" provided by Manticore Search, or use the third-party extension "sphinxapi" to connect and query the Manticore Search service.

The sample code for using the official extension "manticore" is as follows:

// Connect to the Manticore Search service
$conn = new ManticoreSe();
$conn-> ;connect('localhost', 9306);

// Keyword search
$keyword = 'PHP';
$res = $conn->query($keyword, 'my_index' );
if ($res && $res->getTotal() > 0) {

// 遍历搜索结果
foreach ($res->getMatches() as $match) {
    // 处理搜索结果数据
    $id = $match['id'];
    $title = $match['attrs']['title'];
    $content = $match['attrs']['content'];
    // ...
}

}

3. Display based on search results:
   After getting After searching the results, we need to display them accordingly. Here is some sample code to display search results in a unique way.

a) Highlight search keywords:
In search results, highlighting keywords can help users find relevant information more easily. We can use PHP's built-in functions and HTML tags to achieve keyword highlighting.

$highlightedTitle = preg_replace('/('.$keyword.')/i', '$1128dba7a3a77be0113eb0bea6ea0a5d0', $title);
$highlightedContent = preg_replace(' /('.$keyword.')/i', '$1128dba7a3a77be0113eb0bea6ea0a5d0', $content);

echo "684271ed9684bde649abda8831d4d355".$highlightedTitle."9340feb30de26aa770b0867b66da969c";
echo "e388a4556c0f65e1904146cc1a846bee".$highlightedContent."94b3e26ee717c64999d7867364b1b4a3";

b) Sorting and weight display:
Manticore Search allows us to set settings for search results Ranking and weighting. We can use these rankings and weights to display more targeted and customizable search results.

$res->setSortMode(SPH_SORT_ATTR_DESC, 'weight');
$res->setFieldWeights(array('title'=>10, 'content'=>5));

foreach ($res->getMatches() as $match) {

$id = $match['id'];
$title = $match['attrs']['title'];
$content = $match['attrs']['content'];
$weight = $match['weight'];

echo "<h3>".$title."</h3>";
echo "<p>".$content."</p>";
echo "<p>权重: ".$weight."</p>";

}

Conclusion:
By using PHP and Manticore Search, we can easily Develop and optimize the display of search results. By highlighting keywords, ranking and weighting, we can create unique and user-friendly search results pages, improve user experience and provide more accurate information retrieval services. In practical applications, we can further customize the display of search results according to needs to meet the needs of different scenarios.
