[jira] [Commented] (SOLR-7883) MoreLikeThis is incompatible with
facets
[ https://issues.apache.org/jira/browse/SOLR-7883?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15352557#comment-15352557 ]
Michael Daum commented on SOLR-7883:
------------------------------------
This error still persists and can easily be reproduced:
(1) add <requestHandler name="/mlt" class="solr.MoreLikeThisHandler"></requestHandler> to example/techproducts/solr/techproducts/conf/solrconfig.xml
(2) bin/solr -e techproducts
(3) curl "http://localhost:8983/solr/techproducts/mlt?indent=true&q=id%3aSP2514N&mlt.mintf=1&wt=json&mlt.match.include=true&rows=0&mlt.fl=cat&facet=true&facet.field=cat"

> MoreLikeThis is incompatible with facets
> ----------------------------------------
>
> Key: SOLR-7883
> URL: https://issues.apache.org/jira/browse/SOLR-7883
> Project: Solr
> Issue Type: Bug
> Components: faceting, MoreLikeThis
> Affects Versions: 5.2.1
> Environment: Arch Linux / OpenJDK 7.u85_2.6.1-1
> Reporter: Thomas Seidl
> Assignee: Shalin Shekhar Mangar
>
> When using the {{MoreLikeThis}} request handler, it doesn't seem possible to also have facets. This worked in Solr 4, but seems to be broken now.
> Example:
> This works: {{?qt=mlt&q=id:item1&mlt.fl=content}}
> This doesn't: {{?qt=mlt&q=id:item1&mlt.fl=content&facet=true}}
> (Yes, you don't even need to specify any facet fields/ranges/queries. The {{q}} query just has to match an item.)
> While the latter will actually return the same result set as the former, the HTTP status is 500 and the following error included in the response:
> {noformat}
> java.lang.NullPointerException
