Commit 41ecad9897bb8949bfed730cd988aec58aa69775 in lucene-solr's branch refs/heads/master from [~dawid.weiss]
[ https://git-wip-us.apache.org/repos/asf?p=lucene-solr.git;h=41ecad9 ]
SOLR-5351: Fixed More Like This Handler to use all fields provided in mlt.fl when used with content stream. The similarity is calculated between the content stream's value and all fields listed in mlt.fl.

> Key: SOLR-5351
> URL: https://issues.apache.org/jira/browse/SOLR-5351
> Project: Solr
> Issue Type: Bug
> Components: MoreLikeThis
> Affects Versions: 4.4
> Environment: Linux,Windows
> Reporter: Zygmunt Wiercioch
> Assignee: Tommaso Teofili
> Priority: Minor
> Attachments: SOLR-5351.patch, SOLR-5351.patch

> The documentation at: http://wiki.apache.org/solr/MoreLikeThisHandler indicates that one can use multiple fields for similarity in mlt.fl:
> http://localhost:8983/solr/mlt?stream.body=electronics%20memory&mlt.fl=manu,cat&mlt.interestingTerms=list&mlt.mintf=0
> In trying this, only one field is used.
> Looking at the code, it only looks at the first field:
> public DocListAndSet getMoreLikeThis( Reader reader, int start, int rows, List<Query> filters, List<InterestingTerm> terms, int flags ) throws IOException
> {
> // analyzing with the first field: previous (stupid) behavior
> rawMLTQuery = mlt.like(reader, mlt.getFieldNames()[0]);
