【ElasticSearch】文档（删除）单个和批量

1、单个删除文档

rest api

DELETE myindex/_doc/1

java client

DeleteRequest deleteRequest = new DeleteRequest(index, ElasticsearchConstants.INDEX_TYPE, id);
deleteRequest.setRefreshPolicy(WriteRequest.RefreshPolicy.IMMEDIATE);
DeleteResponse deleteResponse = restHighLevelClient.delete(deleteRequest, RequestOptions.DEFAULT);
if (deleteResponse.getResult() == DocWriteResponse.Result.DELETED) {
    log.debug(String.format("删除索引数据成功，index：%s，id：%s", index, id));
    return true;
} else if (deleteResponse.getResult() == DocWriteResponse.Result.NOT_FOUND) {
    log.error(String.format("删除索引数据，id不存在，index：%s，id：%s", index, id));
    return true;
} else {
    log.error(String.format("删除索引数据失败，index：%s，id：%s", index, id));
    return false;
}

 

2、批量删除文档

rest api

POST myindex/_delete_by_query
{
  "query": {
    "bool": {
      "must": [
        {
          "term": {
            "name": {
              "value": "Alice"
            }
          }
        }
      ]
    }
  }
}

java client

BoolQueryBuilder boolQueryBuilder = QueryBuilders.boolQuery();
boolQueryBuilder.must(QueryBuilders.termQuery("name", "Alice"));
DeleteByQueryRequest request = new DeleteByQueryRequest(index);
request.setConflicts("proceed");
request.setQuery(boolQueryBuilder);
BulkByScrollResponse bulkByScrollResponse = restHighLevelClient.deleteByQuery(deleteByQueryRequest, RequestOptions.DEFAULT);
List<BulkItemResponse.Failure> bulkFailures = bulkByScrollResponse.getBulkFailures();
for (BulkItemResponse.Failure bulkFailure : bulkFailures) {
    System.out.println(bulkFailure.getMessage());
}
