: If I want to use MoreLikeThis algorithm I need to add this documents in the : index? The MoreLikeThis will work with soft commits? Is there a solution to : do a MoreLikeThis without adding the document in the index?
you can feed the MoreLikeThisHandler a ContentStream (ie: POST data, or file upload, or "stream.body" request param) of text instead of sending it a query and it will use that raw text to find "more like this" http://wiki.apache.org/solr/MoreLikeThisHandler -Hoss
