Developing search history functionality using PHP and Manticore Search

Developing search history function using PHP and Manticore Search

Overview:
In many applications, the search history function can provide users with a convenient search experience. By recording the user's search history, users can quickly select previous search results and jump to related pages the next time they search. This article will introduce how to develop search history functionality using PHP and Manticore Search.

Requirements:
Before you start, you need to make sure that PHP and Manticore Search have been installed and configured. If Manticore Search has not been installed, you can install and configure it through the official documentation.

Implementation steps:

1. Create search history table
   First, we need to create a table to store search history. Open the Manticore Search console and create the following schema:

index history
{
    source = history
    path = /path/to/your/data/history
    morphology = stem_en
    min_word_len = 1
    html_strip = 1
    stopwords = stopwords_en.txt
    charset_type = utf-8
    enable_star = 1
}

This will create an index named "history" and define where search history is stored and related settings.

2. Front-end interface and user input
   Create a search box on the front-end to allow users to enter search keywords. Send the keywords entered by the user to the back-end PHP script through an AJAX request.
3. PHP back-end processing
   After the PHP script receives the search keyword entered by the user, it needs to perform the following operations:
   3.1 Connect to Manticore Search
   Use the PHP client library of Manticore Search, Connect to the Manticore Search server. The code is as follows:

require_once 'vendor/autoload.php';
use ManticoresearchClient;
$client = new Client();
$client->connect(['host' => 'localhost', 'port' => 9308]);

Please modify the host and port according to the actual situation.

3.2 Search History
Use the search function of Manticore Search to search in the search history table based on the keywords entered by the user. The code is as follows:

$response = $client->search([
    'index' => 'history',
    'query' => [
        'match' => ['keyword' => $keyword]
    ],
    'limit' => 10,
]);

This will match records in the search history table that contain the keyword entered by the user and return up to 10 results.

3.3 Store search history
Next, store the keywords entered by the user into the search history table. You can use code similar to the following:

$client->insert([
    'index' => 'history',
    'doc' => ['keyword' => $keyword]
]);

This will insert the keyword entered by the user into the search history table as a document.

4. Front-end display search history
   First, return the search history results returned by the back-end to the front-end in JSON format. The front end can then use JavaScript to parse and display the search history results.

$.ajax({
    url: 'search_history.php',
    data: { keyword: keyword },
    type: 'POST',
    dataType: 'json',
    success: function(response) {
        // 解析并展示搜索历史记录结果
    }
});

To sum up, we have successfully implemented the search history function using PHP and Manticore Search. Users can enter keywords and search, and the search results will be stored in the search history table. The next time users search again, they can quickly select previous search results. In this way, users can find relevant information more conveniently, which improves user experience.

Note: The code examples are for reference only and may need to be adjusted and optimized according to the actual situation. Please do more development and testing according to your own needs.
