官方文档:https://wiki.apache.org/solr/Atomic_Updates
solrInputDocument.addField("id", id);
Map<String, String > operation = new HashMap<>();
operation.put("set", "test1");
solrInputDocument.addField("title", operation);
solrServer.add(solrInputDocument);
solrServer.commit();
官方文档中,要注意:
The core functionality of atomically updating a document requires that all fields in your SchemaXml must be configured as stored="true"
solr原子更新,支持store=true,如果store为false,更新后字段会丢失。
