Sphinx plugin for CakePHP

For earlier versions of CakePHP (2.x)

Please use the 2.x branch and follow the readme instructions under that for usage instructions

Installation

You can install this plugin into your CakePHP application using composer.

The recommended way to install composer packages is:

composer require voycey/cakephp-sphinxsearch

##Basic Documentation

I designed this as a replacement for the binary API access for Sphinxsearch that I was using on 2.x (https://github.com/voycey/sphinxsearch-cakephp2)

It currently has one function and that is to query the provided index and return the matching records in a CakePHP friendly format (In this case as Query objects and Entities).

##How to use

Install the package with composer as above
Add Plugin::load('Sphinx'); to your bootstrap.php
Attach the behaviour to a table you wish to search on (There must be an index that is generated from this model - the behaviour works by pulling the ID's from Sphinx and then fetching them from the DB (See TODO's for improving this)
Behavior config options:
- 'connection' => ['host' => 'hostname', 'port' => 'port'] (default hostname is 'localhost' and default port is 9306)
- 'defaultIndex' => 'index_name'

<?php 
class PostsTable extends Table
{

    /**
     * Initialize method
     *
     * @param  array $config The configuration for the Table.
     * @return void
     */
    public function initialize(array $config)
    {
        parent::initialize($config);

        $this->table('posts');
        $this->displayField('title');
        $this->primaryKey('id');

        $this->addBehavior('Timestamp');
        $this->addBehavior('Sphinx.Sphinx');
    }
}

Perform a search through the behaviour directly (This will return a query object), it takes an array of the following parameters:
- index - this is the index you want to search against
- term - this is the term you want to search for
- match_fields - these are the fields you want to search against (default is search whole index)
- pagination - this is a standard Cake 3 pagination array - allows you to define how your data comes back, what fields it contains and what Models are contained.
- limit - this is the number of results to limit to, currently defaults to 1000

Here is an example unit test that works for me.

public function testBehaviour()
{
    $paginate = [
        'order' => [
            'Posts.id asc'
        ],
        'fields' => [
            'id', 'title', 'user_id'
        ],
        'contain' => [
            'Comments' => [
                'fields' => ['id', 'post_id']
            ],
            'Categories' => [
                'fields' => ['id', 'CategoriesPosts.post_id']
            ],
            'Types' => [
                'fields' => ['id', 'name']
            ]
        ]
    ];

    $query = $this->Posts->search([
                                    'index' => 'idx_toolkit', 
                                    'term' => 'Ten', 
                                    'match_fields' => 'title', 
                                    'paginate' => $paginate,
                                    'limit' => 50
                                ]);
    
    $row = $query->first();

    $this->assertInstanceOf('Cake\ORM\Query', $query);
    $this->assertInstanceOf('Cake\ORM\Entity', $row);

}

###TODO

Give option for all data to be pulled from Sphinxsearch directly rather than then querying DB
Hook into afterSave and have the Sphinx index updated (this isn't a priority for me as my indexes don't need to be live but please submit a pull request if you want to add this)
Work out how to test this easily on Travis (again - help appreciated)
