[jira] [Commented] (SOLR-5480) Make MoreLikeThisHandler
distributable
[ https://issues.apache.org/jira/browse/SOLR-5480?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14008901#comment-14008901 ]
Markus Jelsma commented on SOLR-5480:
-------------------------------------
Hi Steve, i took your 4.6 patch and applied it to 4.8, i did have to fix some issues that were committed when some deep paging fix was commit. Anyway, the component seems to work but it takes a very long time, over 8 seconds on a powerful cluster. I tracked it down to the shard queries having a rows=20 parameter so i get mlt.count for 20 results per shard, can you confirm?

> The MoreLikeThis component, when used in the standard search handler supports distributed searches. But the MoreLikeThisHandler itself doesn't, which prevents from say, passing in text to perform the query. I'll start looking into adapting the SearchHandler logic to the MoreLikeThisHandler. If anyone has some work done already and want to share, or want to contribute, any help will be welcomed.
