In order for the code bellow to work:

► Make sure to update the variables ("solrUrl", "collectionName", ...) with your information.

► Make sure to add the fields "id", "field1", and "field2" to your SchemaXml.

To force the commit, make sure to set the property "openSearcher" to true (SolrConfigXml file -> updateHandler -> autoCommit)

Note: You can also force the commit by running the URL: http://localhost:8983/solr/COLLECTION-NAME/update?commit=true

Add documents using the request handler /update:
final String UPDATE_REQUEST_PATH = "/update"; final String[] solrUrl = { "http://localhost:8983/solr" }; final String collectionName = "collection1"; final String SOLR_UNIQUE_KEY = "id"; final String FIELD_1 = "field1"; // multiValued=true final String FIELD_2 = "field2"; final String DYNAMIC_FIELD_1 = "dynamicField1_s"; final String DYNAMIC_FIELD_2 = "dynamicField2_s"; final CloudSolrClient cloudSolrClient = new CloudSolrClient.Builder(Arrays.asList(solrUrl)).build(); cloudSolrClient.setDefaultCollection(collectionName); // adding documents [/update] [UpdateRequest::add] [SolrInputDocument] { final SolrInputDocument solrInputDocument = new SolrInputDocument(); solrInputDocument.addField(SOLR_UNIQUE_KEY, "2"); solrInputDocument.addField(DYNAMIC_FIELD_1, "dynamic_field1 1"); solrInputDocument.addField(DYNAMIC_FIELD_2, "dynamic_field2 1"); solrInputDocument.addField(FIELD_1, "field1 1"); solrInputDocument.addField(FIELD_1, "field1 2"); solrInputDocument.addField(FIELD_2, "field2 1"); final UpdateRequest updateRequest = new UpdateRequest(); updateRequest.add(solrInputDocument); updateRequest.setPath(UPDATE_REQUEST_PATH); updateRequest.setMethod(METHOD.POST); final NamedList<Object> response = cloudSolrClient.request(updateRequest); System.out.println(response); } cloudSolrClient.close();
