The MoreLikeThis component actually can accept external input: http://wiki.apache.org/solr/MoreLikeThisHandler#Using_ContentStreams -----Original message----- From: Jonathan Rochkind <rochk...@jhu.edu> Sent: Fri 10-09-2010 18:59 To: solr-user@lucene.apache.org; Subject: RE: How to Update Value of One Field of a Document in Index?
"More like this" is intended to be run at query time. For what reasons are you thinking you want to (re-)index each document based on the results of MoreLikeThis? You're right that that's not what the component is intended for.

Thanks. I am trying to use MoreLikeThis in Solr to find similar documents in the solr index and use the data from these similar documents to modify a field in each document that I am indexing. I found that MoreLikeThis in Solr only works when the document is in the index, is it true? If so, I may have to wait til the indexing is finished, then run my own command to do MoreLikeThis to each document in the index, and then reindex each document? It sounds like it's not efficient. Is there a better way? Thanks. ________________________________ From: Liam O'Boyle <liam.obo...@intelligencebank.com> To: solr-user@lucene.apache.org Cc: u...@nutch.apache.org Sent: Thu, September 9, 2010 11:06:36 PM Subject: Re: How to Update Value of One Field of a Document in Index? Hi Savannah, You can only reindex the entire document; if you only have the ID, then do a search to retrieve the rest of the data, then reindex. This assumes that all of the fields you need to index are stored (so that you can retrieve them) and not just indexed.
