How to do full text search using Sphinx in ThinkPHP6?

In modern Web development, search engines have become an indispensable part. Compared with other search engines, Sphinx is a service specially designed to handle full-text search. In this article, we will introduce in detail how to integrate Sphinx in ThinkPHP6 for full-text search.

1. Installing Sphinx

First, we need to install Sphinx on the server. The following is an example command to install Sphinx on an Ubuntu system:

$ sudo apt-get update
$ sudo apt-get install sphinxsearch

After the installation is complete, we need to specify the data sources we wish to search in the Sphinx configuration file. In Ubuntu, the location of the Sphinx configuration file is usually /etc/sphinxsearch/sphinx.conf. This file contains data source information and other configuration options for Sphinx. We need to adapt it to our needs.

2. Configuring Sphinx Model

There are two ways to use Sphinx for full-text search in ThinkPHP6: use Sphinx Client to search, or inherit the SphinxqlTrait class to define Sphinx Model. Here we introduce the second method.

First, we need to define a SphinxModel. Inherit SphinxqlTrait in the Model class and define the $_table, $_sphinx_index, and $_sphinx_server properties. Here, $_table specifies the table name, $_sphinx_index specifies the index name in the Sphinx data source, and $_sphinx_server is the relevant information of the Sphinx server.

<?php
namespace appmodel;

use thinkmodelconcernSoftDelete;
use thinkmodelconcernTimestamp;
use thinkmodelSphinxqlTrait;

class Article extends     hinkModel
{
    use SphinxqlTrait;

    protected $table = 'article';
    protected $_sphinx_index = 'article';
    protected $_sphinx_server = [
        'host' => '127.0.0.1',
        'port' => 9312,
    ];
}

3. Implementing full-text search

With Sphinx Model, we can easily perform full-text search. The following is an example of using Sphinx Model for keyword query:

use appmodelArticle;

class Search
{
    public static function search($keyword)
    {
        $articles = Article::search($keyword)->select();

        return $articles;
    }
}

In this example, we first introduce the appmodelArticle model, and then use the Article::search($keyword) method in the search function to query, this The parameters of the method are the search keywords. Finally, we return the query results.

4. Conclusion

In this article, we introduced how to use Sphinx for full-text search in ThinkPHP6. We first installed the Sphinx service, then defined a Sphinx Model, and finally we showed how to use the Sphinx Model for full-text search. This method is simple and easy to implement, and can help us handle large-scale full-text search needs. I hope this article can help you.
