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.

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.
