使用Type通配符的Update()也存在该问题,但是我发现DocumentExists()的作用相同,因此在此将问题简化如下:
这有效…
var docExists = client.DocumentExists<object>(d => d .Index(indexname) .Id(myId) .Type("Abcdef"));
但这失败了
var docExists = client.DocumentExists<object>(d => d .Index(indexname) .Id(myId) .Type("Abc*"));
如果我完全省略Type,它也会失败。有人知道如何进行这项工作吗?(即使不管文档的类型如何都可以,对我而言还是可以的。)
据我所知,不可能在类型名称中指定通配符,但是您可以做一些技巧。
您可以在索引中查询具有特定ID的文档,并使用前缀过滤器来缩小对某些类型的搜索范围。
var searchResponse = client.Search<dynamic>(s => s .Type(string.Empty) .Query(q => q.Term("id", 1)) .Filter(f => f.Prefix("_type", "type")));
这是完整的示例:
class Program { static void Main(string[] args) { var indexName = "sampleindex"; var uri = new Uri("http://localhost:9200"); var settings = new ConnectionSettings(uri).SetDefaultIndex(indexName).EnableTrace(); var client = new ElasticClient(settings); client.DeleteIndex(descriptor => descriptor.Index(indexName)); client.CreateIndex(descriptor => descriptor.Index(indexName)); client.Index(new Type1 {Id = 1, Name = "Name1"}, descriptor => descriptor.Index(indexName)); client.Index(new Type1 {Id = 11, Name = "Name2"}, descriptor => descriptor.Index(indexName)); client.Index(new Type2 {Id = 1, City = "City1"}, descriptor => descriptor.Index(indexName)); client.Index(new Type2 {Id = 11, City = "City2"}, descriptor => descriptor.Index(indexName)); client.Index(new OtherType2 {Id = 1}, descriptor => descriptor.Index(indexName)); client.Refresh(); var searchResponse = client.Search<dynamic>(s => s .Type(string.Empty) .Query(q => q.Term("id", 1)) .Filter(f => f.Prefix("_type", "type"))); var objects = searchResponse.Documents.ToList(); } } class Type1 { public int Id { get; set; } public string Name { get; set; } } class Type2 { public int Id { get; set; } public string City { get; set; } } class OtherType2 { public int Id { get; set; } }
对全局没有太多了解,但是也许您可以更改解决方案以使用索引而不是类型?您可以将通配符放在索引名称中。
