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. Article(id, articleBaseId, title, date, ...)

in solr schema.xml file i just define all article field that mixed with ArticleBase table (for use one index on solr) like this: (id, articleBaseId, groupId, ...)

problem: Admin want to change group (ArticleBase), therefore i must update (or replace) all indexed article in solr. right ?
can i update groupId only in solr index ?

have any solution ?

Note:Article table contains more than 200 million article, and i using solr for index only (not store any field data except article id)

You can refer to this documentation for Partial Updates. You can make an update either by replacing it or adding more values to that particular field although (like a list), it's not required in your case

Solr supports different types of Update Operations.

The set of update operations supported by Solr.

'add' - add a new value or values to an existing Solr document field, or add a new field and value(s).

'set' - change the value or values in an existing Solr document field.

'remove' - remove all occurrences of the value or values from an existing Solr document field.

Here is an example of how to do a partial update via Solr’s Java client, SolrJ

// create the SolrJ client
HttpSolrClient solrClient = new HttpSolrClient("http://localhost:8983/solr");
// for clould there is CloudSolrClient api

// create the document
SolrInputDocument solrDocument = new SolrInputDocument();
solrDocument.addField("id","12345");
Map<String,Object> solrUpdates = new HashMap<>(1);
solrUpdates.put("address","Pune");
solrDocument.addField("cat", solrUpdates); 

solrClient.add( solrDocument );  
solrClient.close();
