Description

I have a MoreLikeThis query handler set up on my index:

If I use faceting on a query with no no tagging and exclusion everything works as expected. eg:

/mlt?facet.field=genre&facet.mincount=1&facet=true&fq=genre:{GENRE_VALUE}&indent=true&q.op=OR&q=id:{DOCUMENT_ID}

When I add tagging and exclusion the facet counts are not returned and I get a null pointer exception:

/mlt?facet.field={!ex=g}genre&facet.mincount=1&facet=true&fq={!tag=g}genre:{GENRE_VALUE}&indent=true&q.op=OR&q=id:{DOCUMENT_ID}

Here is the stack trace:
