Let me try my best to make myself understood.
I have a node type Exhibition where I want to display related nodes of type Article, and these related nodes are tagged with taxonomy tags. On the Exhibition node I want a field where I can write one or more words, and related Articles tagged with these words should be displayed.
I want to use the Entity Reference module since this is already in use elsewhere, and I want to limit the number of modules in use. (I know of the Similar By Terms module).
Does anyone know if this is possible?
