":" String "}," raw ": {" type ":" string "," index ":" Not_analyzed "}}}}The above file says that we define its mapping for Index_type, the index type. The point is to map the name field to two, one to name the index analysis, and the other to not analyze raw, which will not split the phrase New York. So when we do the search, we can do the term aggregation for the Name.raw field and get the number of occurrences in all cities. Term Aggregation's The rest method requests are written as follows

They understand how the field being queried are analyzed and would apply each field ' analyzer (or Search_analyzer) to the Q Uery string before executing. 1

可以使用行命令 curl 通过9200端口与 Elasticsearch 的 RESTful API 进行通信。Elasticsearch RESTful API规范例如，计算集群中文件的数量，我们就可以使用： curl -XGET ‘http://localhost:9200/_count?pretty‘-d ‘{ "query": { "match_all": {} }}详细说明：1.相应的 HTTP 请求方法 或者 变量 : GET, POST, PUT, HEAD 或者 DELETE。2.集群中任意一个节点的访问协议、主机名以及端口。3.请求的路径。4.任意一个查询后再加上 ?pretty 就可以生成 更加美观 的JSON

The official PHP API is written in the ribs, and the following class can be manipulated using the ES API. [PHP]View Plaincopyprint?

In the 2.X version, this delete by query function was removed because the official thought it would cause some errors to install the plugin itself if needed.Bin/plugin Install Delete-by-queryWhen you need to useDELETE/Index name/type/_query{"query"needed to be emptied: {"match_all " : {}}}Then in the 5.x version of the API is again the official back to the self-feature.

Elasticsearch JAVA API is extremely extensive, it is obviously not realistic to introduce all the method meanings. From 1.x to 2.x, to 5.x, finally to 6.0, but also in just two or three years, I picked 5.4.0 version of the three parts of the usual use of sorting out, the meaning of the parameters of the method I do not introduce, Elasticsearch basic friends shoul

Elasticsearch is developed in Java, as the current popular enterprise-class search engine, used in cloud computing , can achieve real-time search, and has a stable, reliable, fast installation, ease of use and many other advantages, most enterprises are favor

Elasticsearch supports batch addition or deletion of index documents. In Java APIs, bulkrequestbuilder is constructed, batch index/delete requests are added to bulkrequestbuilder, and bulkrequestbuilder is executed. The following is an example: Import static Org. elasticsearch. common. xcontent. xcontentfactory. *; bulkrequestbuilder bulkrequest = client. preparebulk (); bulkrequest. add (client. prepareind
