[jira] Commented: (SOLR-1085) SolrJ client java does not support moreLikeThis querys and results

    [ https://issues.apache.org/jira/browse/SOLR-1085?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12970487#action_12970487 ] 

Renaud Richardet commented on SOLR-1085:
----------------------------------------

For the record, this workaround (proposed from Bruce Ritchie on http://www.mail-archive.com/solr-user@lucene.apache.org/msg14525.html) worked for me:

#1 - Define the mlt handles in solrconfig.xml (it's not defined in the example 
solrconfig.xml I was using):

<requestHandler name="/mlt" class="solr.MoreLikeThisHandler" />

#2 - with Solrj, access the mlt handler via something similar to the following:

query.setQueryType("/" + MoreLikeThisParams.MLT);
query.set(MoreLikeThisParams.MATCH_INCLUDE, false);
query.set(MoreLikeThisParams.MIN_DOC_FREQ, 1);
query.set(MoreLikeThisParams.MIN_TERM_FREQ, 1);
query.set(MoreLikeThisParams.SIMILARITY_FIELDS, "subject,body");
query.setQuery("Your query here or in my case the unique key field:value");
