[英]LINQ expressions for Elasticsearch NEST query
I setting up an index as below.我设置了一个索引如下。 But now I have a requirement because of which i need to tweak the indexing style.
但是现在我有一个要求,因此我需要调整索引样式。 (i have to add analyzer field in the below code).
(我必须在下面的代码中添加分析器字段)。
Reference[My previous question and its answer]: Elastic Search using NEST - Results different in debug and browser mode参考[我之前的问题及其答案]: 使用 NEST 进行弹性搜索 - 结果在调试和浏览器模式下不同
How can I rewrite我该如何重写
var connectionSettings = new ConnectionSettings(pool)
.DefaultIndex(defaultIndex)
.MapDefaultTypeNames(m => m.Add(typeof(Class1), "omg"))
.PrettyJson()
.DisableDirectStreaming());
with the mapping settings like below.使用如下映射设置。
{
"mappings": {
"Class1": {
"properties": {
"Answer": {
"type": "string",
"analyzer": "english"
}
}
}
}
}
This is my take on answer:这是我对答案的看法:
settings = new ConnectionSettings(pool)
.DefaultIndex(defaultIndex)
.MapDefaultTypeNames(m => m.Add(typeof(Class1), "omg"))
.PrettyJson()
.DisableDirectStreaming();
var descriptor = new CreateIndexDescriptor(defaultIndex)
.Mappings(ms => ms
.Map<Class1>(m => m
.Properties(ps => ps
.String(s=>s
.Name(n=>n.Ans)
.Analyzer("english")))));
I think I'm missing a link somewhere between the index creation and mappings.我想我错过了索引创建和映射之间的某个链接。 Though it didnt show an error while coding, the output is not as expected.
虽然在编码时没有显示错误,但输出并不如预期。
TIA TIA
A CreateIndexDecriptor<T>
is a descriptor for creating an index, but you need to pass it to the IElasticClient.CreateIndex()
method in order to create the index in Elasticsearch. CreateIndexDecriptor<T>
是用于创建索引的描述符,但您需要将其传递给IElasticClient.CreateIndex()
方法以便在 Elasticsearch 中创建索引。
void Main()
{
var defaultIndex = "default-index";
var pool = new SingleNodeConnectionPool(new Uri("http://localhost:9200"));
var settings = new ConnectionSettings(pool, new InMemoryConnection())
.DefaultIndex(defaultIndex)
.MapDefaultTypeNames(m => m.Add(typeof(Class1), "omg"))
.PrettyJson()
.DisableDirectStreaming();
var client = new ElasticClient(settings);
client.CreateIndex("new-index", c => c
.Mappings(ms => ms
.Map<Class1>(m => m
.Properties(ps => ps
.String(s => s
.Name(n => n.Ans)
.Analyzer("english")
)
)
)
)
);
}
public class Class1
{
public string Ans { get; set;}
}
The request to Elasticsearch looks like对 Elasticsearch 的请求看起来像
{
"mappings": {
"omg": {
"properties": {
"ans": {
"type": "string",
"analyzer": "english"
}
}
}
}
}
