solr原子更新-即指定更新某个字段的值

时间:2022-05-10 00:38:40

官方文档:https://wiki.apache.org/solr/Atomic_Updates

SolrInputDocument solrInputDocument  =  new SolrInputDocument ( ) ;
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。
