MLT Component only returns ID and score

Hi,

I've had to switch to using the MLT component, rather than the handler, 
since I'm running on Solrcloud (5.4) and if I hit a node without the 
starting document, I get nothing back.

When I perform a MLT query, I only get back the ID and score for the 
similar documents, yet my fl=*,score.

"moreLikeThis" : [
       "tg-uk-6336277-5820875618687434337",
       {
          "maxScore" : 16.857872,
          "numFound" : 49559,
          "docs" : [
             {
                "score" : 16.857872,
                "id" : "tg-uk-6336277-6676971947462687384"
             },
             {
                "score" : 16.857872,
                "id" : "tg-uk-6336277-1922478172471276129"
             },



Here's my config...

     <requestHandler name="/select" class="solr.SearchHandler">

         <lst name="defaults">

             <str name="defType">edismax</str>

             <str name="echoParams">explicit</str>

             <float name="tie">0.1</float>

             <str name="fl">*,score</str>

             <str name="qf">
                 name^5
                 brand^2
                 category^3
             </str>

             <str name="df">name</str>

             <str name="mm">100%</str>

             <int name="ps">100</int>

             <str name="q.alt">*:*</str>

             <str name="mlt.qf">
                 name^5 description^2 brand^3 category^3
             </str>

             <str 
name="mlt.fl">name,description,ean,upc,asin,brand,category</str>

         </lst>

         <arr name="components">
             <str>query</str>
             <str>facet</str>
             <str>mlt</str>
         </arr>

     </requestHandler>

Thanks for the info, does this replace the mlt component?  ie, can I 
remove that component from being loaded/used?

These are my parameters, the results look okay, just want to ensure I'm 
using it right...


           fq => [
                   'market:uk'
                 ],
           q => '{!mlt 
qf=name,description,brand,category,ean,upc,asin}az-uk-b017u8thna',
           rows => 10,
           start => 0,
           wt => 'json'

Re: MLT Component only returns ID and score

Try the MLT query parser, which is a much newer way of doing this.
Perhaps it will work better for you.
