Now it is hardcoded to DEFAULT_DIM_CONFIG. This may be useful for most standard approaches.
However, I use lots of facets. These facets can be multivalued, I do not know that on beforehand. So what I would like to do is to change the default config to mulitvalued = true.
Currently I have a working, but rather ugly workaround that subclasses FacetConfig, like this:
I created a patch to illustrate what I would like to change. By making a protected method it is easier to create a custom subclass of FacetConfig.
Also, maybe there are better way to accomplish my goal (easy default to multivalue?)
