reindexing json object into solr by adding only unique elements

I have indexed json object into solr using httpclient and when I tried to index again, duplicate records are getting indexed.

So how to update the records into solr, everytime I index I want to update the records.

Thanks in advance

In your JSON Object include an ID field inside your json object and it should be unique, for example some random number like 65746 . When you will try to index this document again, solr will check for id .If id is same, solr will not index that whole document again . Now the question is how you declare a unique field in solr schema . So for that go to your schema.xml file or managed-schema file which is inside your core configuration and define unique field like this id . Now solr will identify id coming from your JSON as unique , and won't indexed already indexed documents.Hence there will be no duplicate records. Let me know if that helped you :)
