Getting "explain" information of more like this search in a more usable format

Hi,

I'm executing a more like this search using the MoreLikeThisHandler. I can add "score" to the fields to be returned, but that's all I could find about getting information about how/why documents match. I would like to give my users more hints why documents are similar, so I would like to display important overlapping terms. If I specify debugQuery=true the result contains a "explain" section which is quite detailed, but in a text format I would have to parse. Is there a way to get this kind of information in a more usable way which does not force me to use a debug-flag? I'm mainly interested in showing the terms which each result document has in common with the reference document.

regards,
Achim

Try debug.explain.structured=true, which will give you an XML response that 
can be traversed.

Don't worry about the fact that these features are labeled "debug" - they 
are there simply to explain what is happening. Is there some particular 
concern you have about them being labeled "debug"? Although, you are not the 
first person to complain! What if Solr simply renamed these features with 
the term "detail" instead of "debug" - would that cure your concern?!

Sorry, forget what I said, I totally overlook you where using MLT, and
it does not seem possible to combine it with highlighting.
