How to install

The preferred (and only supported) way of installing charcoal-search is with composer:

★ composer require locomotivemtl/charcoal-search

Dependencies

• PHP 5.5+
• locomotivemtl/charcoal-core
• locomotivemtl/charcoal-base

Example usage

use \Charcoal\Search\SearchRunner;

use \Foo\Bar\CustomObject;

$searchRunner = new SearchRunner([
    'search_config' => [
        'ident'    => 'my-custom-search',
        'searches' => [
            'foo'  => new CustomSearch([
                'logger'   => $logger
                'callback' => function($keyword) {

                }
            ])
        ]
    ],
    'model_factory' => $modelFactory,
    'logger'        => $logger
]);

// The results are an array like `['foo'=>[...], 'bar'=>[...]]`
$results = $searchRunner->search($keyword);

// Access log
$log = $searchRunner->searchLog();

// Differed access to results
$results = $searchRunner->results();

Constructor options

The SearchRunner is instanciated with a single parameter, which contains the constructor options and class dependencies:

Ident	Type	Description
logger	\Psr\Log\LoggerInterface	A PSR-3 logger.
model_factory	\Charcoal\Factory\FactoryInterface	A factory to create objects (and logs).
search_config	array	A search config object

Search config

The search config object contains the search ident as well as the various searches to run on objects.

Ident	Type	Description
ident	string
searches	array	The various searches to perform.

Search types

Available search types, which are defined in the search config's searches:

• custom
• table (todo)
• model (todo)

Custom search

The custom search defines a callback function. This can either be a callable (a method or an object with an __invoke method) or a string (which will attempt to call the function of matching name on the Search Runner object).

The callback method must have the following signature: array callback(string $keyword);

Custom options

Ident	Type	Description
callback	callback	Optional callback to defer searching to.

Table search

The table search is still todo.

Model search

The model search is still todo.

Search log

Every search is automatically logged to (SQL) storage.

Charcoal-admin integration

The search-log object comes by default with full metadata to display in charcoal-admin. Visit at [[your-site.com]]/admin/object/collection?obj-type=charcoal/search/search-log.

There are 2 widgets also available to visualize logs:

• charcoal/admin/widget/search/no-results-search

★ composer test

Development dependencies

• phpunit/phpunit
• squizlabs/php_codesniffer
• satooshi/php-coveralls

Continuous Integration

Service	Badge	Description
Travis		Runs code sniff check and unit tests. Auto-generates API documentation.
Scrutinizer		Code quality checker. Also validates API documentation quality.
Coveralls		Unit Tests code coverage.
Sensiolabs		Another code quality checker, focused on PHP.

Coding Style

All Charcoal modules follow the same coding style and charcoal-search is no exception. For PHP:

• PSR-1
• PSR-2
• PSR-4, autoloading is therefore provided by Composer
• phpDocumentor
