Customize search sorting

You can customize the Sort by menu in the back office search result page, for example, by adding new sort criteria.

To do it, you must create a service that implements the Ibexa\Contracts\Search\SortingDefinition\SortingDefinitionProviderInterface and tag it with ibexa.search.sorting_definition.provider.

The following example class implements SortingDefinitionProviderInterface::getSortingDefinitions, and adds two definitions to sort by section name. A sorting definition contains an identifier, a menu label, a list of content search Sort Clauses, which could be either default or custom, and a priority value to position them in the menu. It also implements TranslationContainerInterface::getTranslationMessages to provide two default English translations in the ibexa_search namespace.

Create the src/Search/SortingDefinition/Provider/SectionNameSortingDefinitionProvider.php file:

[[= include_file('code_samples/back_office/search/src/Search/SortingDefinition/Provider/SectionNameSortingDefinitionProvider.php') =]]

Then add a service definition to config/services.yaml:

services:
    #…
[[= include_file('code_samples/back_office/search/config/append_to_services.yaml', 29, 32) =]]

You can extract a translation file with the translation:extract command, for example, php bin/console translation:extract en --dir=src --output-dir=translations to obtain the translations/ibexa_search.en.xlf file. You could also create it manually, as translations/messages.en.yaml file with the following contents:

[[= include_file('code_samples/back_office/search/translations/messages.en.yaml') =]]
