> The newly introduced MoreLikeThis Query Parser (SOLR-6248) does not return 
> any results when supplied with multiple fields in the {{qf}} parameter.
> To reproduce within the techproducts example, compare:
> {code}
> curl 
> 'http://localhost:8983/solr/techproducts/select?q=%7B!mlt+qf=name%7DMA147LL/A'
> curl 
> 'http://localhost:8983/solr/techproducts/select?q=%7B!mlt+qf=features%7DMA147LL/A'
> curl 
> 'http://localhost:8983/solr/techproducts/select?q=%7B!mlt+qf=name,features%7DMA147LL/A'
> {code}
> The first two queries return 8 and 5 results, respectively. The third query 
> doesn't return any results (not even the matched document).
> In contrast, the MoreLikeThis Handler works as expected (accounting for the 
> default {{mintf}} and {{mindf}} values in SimpleMLTQParser):
> {code}
> curl 
> 'http://localhost:8983/solr/techproducts/mlt?q=id:MA147LL/A&mlt.fl=name&mlt.mintf=1&mlt.mindf=1'
> curl 
> 'http://localhost:8983/solr/techproducts/mlt?q=id:MA147LL/A&mlt.fl=features&mlt.mintf=1&mlt.mindf=1'
> curl 
> 'http://localhost:8983/solr/techproducts/mlt?q=id:MA147LL/A&mlt.fl=name,features&mlt.mintf=1&mlt.mindf=1'
> {code}
> After adding the following line to 
> {{example/techproducts/solr/techproducts/conf/solrconfig.xml}}:
> {code:language=XML}
> <requestHandler name="/mlt" class="solr.MoreLikeThisHandler" />
> {code}
> The first two queries return 7 and 4 results, respectively (excluding the 
> matched document). The third query returns 7 results, as one would expect.
