Thank you for the quick response.
But this will create different search pages right?
Is there any possibility to add 3 search options on one page?
Thanks Rick for an alternative solution depending on your output.
Responsive help enables users to filter the content so the filters could be Door, Cameras and Areas. With a filter applied, only those topics are searched.
Would that work for you?
