Filters in AEM Collections

@lukasz-m @pankajpr @ravi_joshi @asifchowdhury would you please take a moment to review this question? We would be grateful if you could share your suggestion on this question.

Hi @gokulakannanv,

I think what would you like to achieve would be very difficult, or will break some fundamental rules in AEM. Let me explain the complexity below.

1. Unlike Asset search or Lanches etc filters set for Collection view is not included in Search Forms, which would allow you to extend/modify filter set in very easy way.
2. In theory you could try to modify Collection search filters programmatically, but this takes us into another limitation. Configuration for Collection view can be found under /libs/settings/dam/search/collections/jcr:content/items, the problem is that this section is marked as granite:InternalArea, which means you should not overlay this area. Or you are doing it on your own risk.
   
   
   
   
   
3. Last but not least, even if you will decide to overlay above section and extend OOTB set of filters, this could be also a challenging exercise. It's because private and public collections are not distinguish by property but by path, so build a proper query that will limit the results will be difficult.
   

Having above knowledge, and keeping in mind what is available OOTB, I would suggest below approach:

1. Create two tags, one for public collection, and the other for private
2. Use above tags to mark specific collection as public or private
3. Use OOTB Tag filtering on search level.

Of course the solution is not ideal, and would requires some maintenance, but technically it is 100% OOTB solution. Which also have some additional benefits, like the fact you do not have to check this solution after AEM or SP upgrade.
