             Summary: MoreLikeThis Query Parser does not handle multiple field names
                 Key: SOLR-7143
                 URL: https://issues.apache.org/jira/browse/SOLR-7143
             Project: Solr
          Issue Type: Bug
          Components: query parsers
    Affects Versions: 5.0
            Reporter: Jens Wille


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.
