ElasticSearch:写入后立即查询数据

我有一个要求，在写入ES后，能够立即按键读取数据。这可能吗？注意，DataMap是键值对，而_id是到密钥字段的路径。

string v = "Foobar" + i;
string k = Security.Hash(Encoding.UTF8.GetBytes(v));
var data = new DataMap { Key = k, Value = v };
var index = _esclient.Index(data);
// fetch by k
var results = _esclient.Search<DataMap>(p => p
        .Size(1000)
        .Fields(f => f.Key, f => f.Value)
        .Query(q => q.Term("key", k))
        );
// Make sure the record is found
if (!results.Hits.Any())
{
    Console.WriteLine("{0} {1} not found", k, v);
}
