How to Optimize SuiteCRM’s Search Function with PHP

How to optimize the search function of SuiteCRM through PHP

SuiteCRM is an open source customer relationship management software with a powerful search function that can help users quickly find the information they need. However, as the amount of data increases and the number of users increases, the search functionality may become slow or inflexible. In order to improve the performance and accuracy of search, we can optimize SuiteCRM's search function through PHP programming.

1. Using Index

SuiteCRM uses the full-text search function of the database by default to implement search, but it may not work well on large data sets. We can speed up searches by creating our own index. First, we need to create a new table in the database to store search keywords and corresponding record IDs. Then, every time a new record is inserted or updated, we need to update this table. When a user performs a search, we only need to query this index table instead of the entire data table, thereby improving search performance.

The following is a sample code using a MySQL database:

// 创建索引表
$indexTable = 'search_index';
$sql = "CREATE TABLE IF NOT EXISTS {$indexTable} (
        keyword VARCHAR(255) NOT NULL,
        record_id INT(10) UNSIGNED NOT NULL,
        PRIMARY KEY (keyword, record_id)
)";
$db->query($sql);

// 更新索引表
function updateIndex($record_id, $content) {
    // 清除旧的记录
    $sql = "DELETE FROM {$indexTable} WHERE record_id = {$record_id}";
    $db->query($sql);
    
    // 提取关键词
    $keywords = extractKeywords($content);
    
    // 插入新的记录
    foreach ($keywords as $keyword) {
        $sql = "INSERT INTO {$indexTable} (keyword, record_id) VALUES ('{$keyword}', {$record_id})";
        $db->query($sql);
    }
}

// 进行搜索
function search($keyword) {
    $sql = "SELECT * FROM {$indexTable} WHERE keyword LIKE '%{$keyword}%'";
    $result = $db->query($sql);
    
    // 返回匹配的记录
    $records = [];
    while ($row = $result->fetch_assoc()) {
        $record_id = $row['record_id'];
        $record = getRecord($record_id);
        $records[] = $record;
    }
    
    return $records;
}

2. Using cache

The search function of SuiteCRM may need to query the database multiple times, which Will reduce performance. In order to reduce the number of database queries, we can use caching. When a user performs a search, we first check whether there is a matching result in the cache. If so, we return it directly. If not, we perform a database query and store the result in the cache. In this way, we only need to query the database once for multiple identical search requests, which greatly improves search performance.

The following is a sample code using Memcached caching:

// 初始化缓存
$cache = new Memcached();
$cache->addServer('localhost', 11211);

// 进行搜索
function search($keyword) {
    $key = 'search:'.$keyword;
    $records = $cache->get($key);
    
    if (!$records) {
        $sql = "SELECT * FROM {$table} WHERE content LIKE '%{$keyword}%'";
        $result = $db->query($sql);
        
        // 获取匹配的记录
        $records = [];
        while ($row = $result->fetch_assoc()) {
            $record_id = $row['record_id'];
            $record = getRecord($record_id);
            $records[] = $record;
        }
        
        // 存入缓存
        $cache->set($key, $records, 3600);
    }
    
    return $records;
}

By using indexing and caching, we can significantly improve the performance and accuracy of SuiteCRM's search functionality. These optimization methods can be adjusted and expanded based on specific situations to meet different needs and improve user experience. Hope the above sample code can help you.
