Tags from the Default Tag Namespace are not working for searching

Hello everyone,

I'm trying to customise the default search page on the siteadmin section. I've tried to add the default tag namespace ("Standard Tag") to the search form but looks like it doesn't work.

I mean the default namespace has been added but I can't find the pages that conain tags in the default namespace.

Maybe it is some kind of a bug, because the search works fine for my custom namespaces.

The search tags have been extended in the following node:

/libs/wcm/core/content/search/searchpanel/facets/tagoption

.. where the optionsPaths property has been changed to /etc/tags/default

So, if it's a feature of the default tag namespace that's fine but in this case I need to know how to change the default namespace for non-existing tags that users could add using the page properties dialog.

Any help is really appreciated

P.s. Just in case, I'm using CQ 5.6.1
