Is there way to deliver custom facet type without patching ES? I developed  
a new facet type needed for my project, but I have to patch FacetModule's  
constructor (add to processors) to get it working.

It would be nice to declaratively add new facets thru configuration or  
plugin infrastructure. Any plans on that?

Thanks

Igor,

You can add your facet using plugin infrastructure. If you are using 0.19  
or later, all you have to do is add the following method to your Plugin  
class:

```
public void onModule(FacetModule facetModule) {
    facetModule.addFacetProcessor(MyFacetsProcessor.class);
}

```

Before 0.19 you can do the same thing using processModule method.

Igor
