How to use

thrift config

in order to use thrift,you have to config to support cluster
first download the thrift-plugin
second edit the config/elasticsearch.yml with below:

  thrift.port : 9500

  thrift.protocol : ‘binary’

client config

edit the cluster config file:ElasticSearch.config
you can specify the cluster,and nodes,and also config the connection pool,and you can even specify the socket settings
here is simple example

<?xml version="1.0" encoding="utf-8"?>
<ElasticSearchConfig>  
  <Clusters>
    <Cluster Name="Prod">
      <TransportType>Thrift</TransportType>
      <ThriftNodes>
        <Node Host="127.0.0.1" Port="9500" Enabled="true" IsFramed="false" >         
        </Node>
      </ThriftNodes>      
    </Cluster>
    <Cluster Name="localhost">
      <TransportType>Http</TransportType>
      <HttpNodes>
        <Node Host="localhost" Port="9200" Enabled="true"  >          
        </Node>
      </HttpNodes>      
    </Cluster>
  </Clusters>  
</ElasticSearchConfig>

and now rock with elasticsearch.net

var client = new ElasticSearchClient(“localhost”);

CreateIndex:

      client.CreateIndex(“index”, new IndexSetting(5, 1));
ModifyIndex:

      client.ModifyIndex(index, new IndexSetting(10, 2));
DeleteIndex:

      client.DeleteIndex(“index”);
CreateMapping:

      var index = “index_operate” + Guid.NewGuid().ToString();

			StringFieldSetting stringFieldSetting = new StringFieldSetting() { Analyzer = “standard”, Type = “string”, NullValue = “mystr” };
TypeSetting typeSetting = new TypeSetting(“custom_type”);

			typeSetting.AddFieldSetting(“medcl”, stringFieldSetting);
var typeSetting2 = new TypeSetting(“hell_type1”);

			var numfield = new NumberFieldSetting() { Store = Store.yes, NullValue = 0.00 };

			typeSetting2.AddFieldSetting(“name”, numfield);
var result = client.PutMapping(index, typeSetting);
Index:

      client.Index(“testindex”, “testtype”, “testkey”, “{\”a\“:\”b\“}”);

Search:

      client.Search(“testindex”, “testtype”, “_id:testkey”);

Delete:

      client.Delete(“testindex”, “testtype”, “testkey”);

Get:

      client.Get(“testindex”, “testtype”, “testkey”);

check my tests for more example!

elasticsearch.net's Issues

index:analyzed is always sent for _mapping which causes "field can't be tokenized" error

Starting elasticsearch 0.90.5 the mapping is verified and if a primitive (like bool) is sent with index:analyzed then an error is received - field can't be tokenized.

The problem is that the AbstractFieldSetting contains Index field that gets serialized in all classes that inherit from it.

Querying Geo locations

Hi, I was looking for a .net api to elastic search and found this project. I have a question though. I need to use geo location search for distance. How can I do that with this library?

Thanks for this library!

How should I put, Multiple Search Criteria in Single Query.

For example,

I want to make Text query with multiple search criteria nested with AND or OR operator.
not only on one key and value.

Please help me out for this problem.

Version Exposed as an Int32 Type

While indexing documents into Elasticsearch, I can pass an external version with the document being indexed. The reason I want to do this is because I can get various versions of the same document in a span of few seconds or even quicker than that and there is no way I can control the order in which these versions get indexed.

To make sure the index always reflects latest state of the document, I thought I could use the last modified datetime stamp in the document, convert it to a sortable datetime integer (e.g. dateTime.ToString("yyyyMMddHHmmssFFF") gives me 20140427101814673) and pass it on to Elasticsearch as an external version when indexing a document.

Elasticsearch provides a very clean versioning capability that fits nicely into my requirement - the problem however is that Elasticsearch.NET limits this functionality by exposing version as an integer based type which cannot take the large numbers I am trying to pass.
