Update specific field on SOLR index

Question

I want to using solr for search on articles

I have 3 table:

1. Group (id , group name)
2. ArticleBase (id, groupId, some other field)
3. Arti

Answer 1

Solr does not support updating individual fields yet, but there is a JIRA issue about this (almost 3 years old as of this writing).

Until this is implemented, you have to update the whole document.

UPDATE: as of Solr 4+ this is implemented, here's the documentation.
