What is the solution for deprecated getSearchContext() after 4.3?

Are you talking about ModelAdmin::getSearchContext() ? (just checking, as there are multiple classes which have a method with this name).

If so, then the deprecation notice provides the hint:

 Deprecation::notice('4.3', 'Will be removed in favor of GridFieldFilterHeader in 5.0');

There’s a bit of discussion about the situation here:

## Affected Version v4.3.0 ## Description When extending ModelAdmin to add… new pre-defined queries (e.g. a checkbox that will be used to filter adresses in Belgium - using later on the getlist function), the overwritten getSearchContext functions never called. This is the code I used but you may simply use examples from your on-line developers doc (https://docs.silverstripe.org/en/4/developer_guides/customising_the_admin_interface/modeladmin/). ```php class Adress_Admin extends ModelAdmin { private static $url_segment = 'Adress'; private static $menu_title = 'Adressen'; private static $managed_models = [Adress::class]; public function getSearchContext() { $context = parent::getSearchContext(); if($this->modelClass == 'bpf\Adress') { $context->getFields()->push(new CheckboxField('q[InBelgiumA]', 'Only expensive stuff')); } return $context; } ``` ## Steps to Reproduce It's very easy to check - use e.g. error_log to trace the fact the function has been called. Help us with step-by-step instructions. ps: I know this will be depreciated in v5 but at least could you please provide an updated documentation on how to do it using GridfieldFilterHeader. Thank you!!!

That also has some code snippets regarding how to use GridFieldFilterHeader from people who have encountered the same question.

Thank you very much. I am migrating from 4.1 to 4.7.
