4. Filter field definition

4.1. Available filter types

• sonata_search_elastica_boolean: depends on the sonata_type_filter_default Form Type, renders yes or no field,
• sonata_search_elastica_callback: depends on the sonata_type_filter_default Form Type,
• sonata_search_elastica_choice: depends on the sonata_type_filter_default Form Type,
• sonata_search_elastica_string: depends on the sonata_type_filter_choice Form Type,
• sonata_search_elastica_number: depends on the sonata_type_filter_number Form Type,
• sonata_search_elastica_date : depends on the sonata_type_filter_date From Type, renders a date field,
• sonata_search_elastica_date_range : depends on the sonata_type_filter_date_range From Type, renders a 2 date fields,
• sonata_search_elastica_datetime : depends on the sonata_type_filter_datetime From Type, renders a datetime field,
• sonata_search_elastica_datetime_range : depends on the sonata_type_filter_datetime_range From Type, renders a 2 datetime fields.

4.1.1. Callback

To create a custom callback filter, you just need to set the “callback” filter option to a valid callback function. First argument of this function will be Sonata\AdminSearchBundle\ProxyQuery\ElasticaProxyQuery instance which could be modified according to your needs:

namespace Sonata\NewsBundle\Admin;

Sonata\AdminBundle\Admin\AbstractAdmin;
use Sonata\AdminBundle\Datagrid\DatagridMapper;
use Sonata\AdminSearchBundle\ProxyQuery\ElasticaProxyQuery;

final class PostAdmin extends AbstractAdmin
{
    protected function configureDatagridFilters(DatagridMapper $datagridMapper)
    {
        $datagridMapper
            ->add('title')
            ->add('name', Sonata\AdminSearchBundle\Filter\CallbackFilter::class, [
                'callback' => function (ElasticaProxyQuery $query, $alias, $field, $data) {
                    if (!$data || !is_array($data) || !array_key_exists('value', $data)) {
                        return;
                    }

                    $queryBuilder = new \Elastica\Query\Builder();

                    $queryBuilder
                        ->fieldOpen('multi_match')
                            ->field('query', trim($data['value']))
                            ->field('fields', ['name', 'name.std'])
                            ->field('operator', 'and')
                        ->fieldClose();

                    $query->addMust($queryBuilder);
                }
            ])
        ;
    }
}

4.1.2. Date

To make query on date/datetime type, you can use one of the sonata_search_elastica_date filter types. For example if you have a date in the ISO 8601 date format:

protected function configureDatagridFilters(DatagridMapper $datagridMapper)
{
    $datagridMapper
        ->add('date', Sonata\AdminSearchBundle\Filter\DateTimeFilter::class, null, 'datetime', [
            'format' => 'c',
        ])
    ;
}

The format must be a string formatted according to the php format date and be the one used to map the data in elasticsearch. If it is not the same, ElasticSearch will raise an exception failed to parse date field [15/05/28] Invalid format.
