How do I assign 'all' term to a node? I have a vocabulary (lets name it as 'Brands') which is getting filled by adding terms while creating a nodes. 

I have a view which shows me the list of those nodes. This view has an exposed filters including the one filters nodes by Brand. There are nodes which must relate to all 'Brands'. 

It is not possible to assign manually all existing brands to node while creating it because the vocabulary is kinda dynamic. That means they should pass filter with any term checked. Not when 'All', but when any of existing. It seems to be obvious but I can't see any way I can do that.
it was so stupidly simple... Just don't add any term and add a filter to the view 

having Brand one of .... OR having Brand empty(NULL)

I should definitely stop looking for a complex solutions for a simple questions. Thanks anyway
