PHP and Manticore Search Development: Key Tips for Customizing Search Results Pages

WBOYOriginal: 2023-08-05 13:07:421172browse

Introduction:
Manticore Search is a high-performance, powerful full-text search engine, and PHP is a widely used scripting language . Combining these two tools, we can easily build an efficient search results page. This article will introduce some key tips to help you customize your search results page.

1. Install Manticore Search
First, you need to install Manticore Search. You can download the installation package from the official website (https://www.manticoresearch.com/) and follow the instructions to install it. After the installation is complete, you can use the following command to start the Manticore Search service:

sudo systemctl start manticore

2. Indexing
Before you start, you need to index the data for effective search. Manticore Search supports a variety of data sources, such as MySQL, PostgreSQL, and CSV files. Here we take MySQL as an example.

First, you need to create a configuration file, such as manticore.conf, where you specify the details of connecting to the MySQL database:

source manticore {
    type                    = mysql
    sql_host                = localhost
    sql_user                = your_username
    sql_pass                = your_password
    sql_db                  = your_database_name
}

Then, you can use the following Command to build the index:

index your_index_name
{
    type                = plain
    source              = manticore
    path                = /var/lib/manticore/your_index_name
    min_infix_len       = 2
    docinfo             = extern
    mlock               = 0
    morphology          = stem_en
}

Please make sure to modify your_username, your_password, your_database_name and your_index_name in the above code for your own value.

Next, you can use the following command to create the index:

indexer --config /path/to/manticore.conf --all

3. PHP search page
Once your index is established, you can write PHP code to implement the search page . Here is an example:

<?php
require_once('Manticore.php');

$index = 'your_index_name';
$host = 'localhost';
$port = 9306;

$query = isset($_GET['q']) ? $_GET['q'] : '';
$page = isset($_GET['page']) ? $_GET['page'] : 1;

$manticore = new Manticore($host, $port);

$results = $manticore->search($index, $query, $page, 10);

$hits = $results['total'];
$pages = ceil($hits / 10);

foreach ($results['matches'] as $match) {
    // 处理搜索结果
    echo $match['id'].": ".$match['weight']."<br>";
}

// 翻页功能
$startPage = max($page - 5, 1);
$endPage = min($page + 5, $pages);

echo "<div class='pagination'>";
if ($page > 1) {
    echo "<a href='?q=$query&page=".($page-1)."'>上一页</a>";
}
for ($i = $startPage; $i <= $endPage; $i++) {
    echo "<a href='?q=$query&page=$i'>$i</a>";
}
if ($page < $pages) {
    echo "<a href='?q=$query&page=".($page+1)."'>下一页</a>";
}
echo "</div>";

In the above code, your_index_name needs to be replaced with your own index name. $query in the code gets the search keyword entered by the user, and $page gets the number of pages on the current page. Manticore.php is a simple PHP class used to interact with Manticore Search.

4. Customize the search results page
In the search results page, you can customize the display method of the search results according to your needs. For example, you can use HTML and CSS styles to enhance the appearance of search results, or add other features to enhance the user experience.

The following is a simple example showing how to use HTML and CSS to style a search results page:

<!DOCTYPE html>
<html>
<head>
    <title>搜索结果</title>
    <style>
        .result {
            margin-bottom: 10px;
            padding: 10px;
            border: 1px solid #ccc;
        }
        .result h3 {
            margin-top: 0;
        }
        .pagination {
            margin-top: 10px;
            text-align: center;
        }
    </style>
</head>
<body>
    <h1>搜索结果</h1>

    <?php foreach ($results['matches'] as $match): ?>
        <div class="result">
            <h3><?php echo $match['id']; ?></h3>
            <p><?php echo $match['weight']; ?></p>
        </div>
    <?php endforeach; ?>

    <div class="pagination">
        <?php if ($page > 1): ?>
            <a href="?q=<?php echo $query; ?>&page=<?php echo ($page-1); ?>">上一页</a>
        <?php endif; ?>
        <?php for ($i = $startPage; $i <= $endPage; $i++): ?>
            <a href="?q=<?php echo $query; ?>&page=<?php echo $i; ?>"><?php echo $i; ?></a>
        <?php endfor; ?>
        <?php if ($page < $pages): ?>
            <a href="?q=<?php echo $query; ?>&page=<?php echo ($page+1); ?>">下一页</a>
        <?php endif; ?>
    </div>
</body>
</html>

In the above code, we define the .result style To set the appearance of search results, the .pagination style is defined to set the appearance of the paginator.
