I have a MoreLikeThis query handler set up on my index:
<requestHandler name="/mlt" class="solr.MoreLikeThisHandler">
<lst name="defaults">
<str name="echoParams">all</str>
<int name="rows">10</int>
<str name="mlt.fl">text</str>
</lst>
</requestHandler>
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}
If 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}
This is the stack trace:
