[jira] [Commented] (SOLR-5351) More Like This Handler uses only
first field in mlt.fl when using stream.body
[ https://issues.apache.org/jira/browse/SOLR-5351?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14557727#comment-14557727 ]
Kais Hassan commented on SOLR-5351:
-----------------------------------
Thanks Upayavira for your solution, I tried it with Solr 4.10 and it works well. I agree with Tommaso, this should be handled at the Lucene level.

> 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
>
> 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 firs 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]);
