I've been trying to get "More like this" running under solr 3.5. I get the
Exception below. The http request is also highlighted below.
I've looked at the FieldType code and I don't understand what's going on there.
So, while I know what a null pointer exception means, it isn't telling me what
I did or didn't do.
FYI - the "Body" field has termVectors set to "true" which I thought was
sufficient for MLT.
What I'm trying to do is submit the phrase "country now is the time country" to
MLT to determine the "interesting words" (which I want returned) and then
return the top most relevant documents.
Any help on what might be wrong would be appreciated.
