Elasticsearch是一个全文搜索引擎。安装Elasticsearch时需要先安装Java。
wget https://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-1.4.2.zip
unzip elasticsearch-1.4.2.zip
cd elasticsearch-1.4.2
./bin/elasticsearch
安装Marvel
Marvel是一个管理和监控Elasticsearch的工具。它提供一个叫Sense的交互式接口方便通过浏览器与Elasticsearch交互。
bin/plugin -i elasticsearch/marvel/latest
如果不想使用Marvel监控本地集群，可以使用如下方式关闭Marvel监控
echo 'marvel.agent.enabled: false' >> ./config/elasticsearch.yml可以通过前台的方式启动Elasticsearch
bin]$ sudo ./elasticsearch
使用-d参数可以将Elasticsearch放到后台运行
bin]$ sudo ./elasticsearch -d
查看Elasticsearch中的数据
$ curl "http://localhost:9200/?pretty"
{
"status" : 200,
"name" : "xxx",
"cluster_name" : "elasticsearch",
"version" : {
"number" : "1.4.2",
"build_hash" : "927caff6f05403e936c20bf4529f144f0c89fd8c",
"build_timestamp" : "2014-12-16T14:11:12Z",
"build_snapshot" : false,
"lucene_version" : "4.10.2"
},
"tagline" : "You Know, for Search"
}
通过config/elasticsearch.yml设置cluster.name和node.name
可以通过以下方式关闭Elasticsearch
curl -XPOST 'http://localhost:9200/_shutdown'
Talking to Elasticsearch
根据是否使用Java语言，与Elasticsearch交互有几种方法，如果是Java API参见文档
http://www.elasticsearch.org/guide/en/elasticsearch/client/java-api/current/index.html
如果使用其他语言，则使用Elasticsearch提供的RESTFUL API，或者可以直接使用linux命令curl访问
curl -X<VERB> '<PROTOCOL>://<HOST>:<PORT>/?<QUERY_STRING>' -d '<BODY>'
VER HTTP请求方式，GET,POST,PUT,HEAD或DELETE
PROTOCOL 使用HTTP或者HTTPS
HOST Elasticsearch集群中的任意一个node的主机名，如果是在node本机就直接使用localhost
PORT Elasticsearch运行HTTP服务的端口，默认是9200
QUERY_STRING 查询参数
BODY JSON格式的请求数据
$ curl -XGET 'http://localhost:9200/_count?pretty' -d '
{
"query": {
"match_all": {}
}
}
'
{
"count" : 22692,
"_shards" : {
"total" : 3,
"successful" : 3,
"failed" : 0
}
}
$ curl -i -XGET 'localhost:9200/'
HTTP/1.1 200 OK
Content-Type: application/json; charset=UTF-8
Content-Length: 334
{
"status" : 200,
"name" : "jidong",
"cluster_name" : "elasticsearch",
"version" : {
"number" : "1.4.2",
"build_hash" : "927caff6f05403e936c20bf4529f144f0c89fd8c",
"build_timestamp" : "2014-12-16T14:11:12Z",
"build_snapshot" : false,
"lucene_version" : "4.10.2"
},
"tagline" : "You Know, for Search"
}

通过Marvel的Sense接口访问Elasticsearch
http://xxxx.com:9200/_plugin/marvel/sense/index.html
以下直接使用GET或PUT的简略形式，都是直接使用Marvel的Sense接口访问Elasticsearch，可以点击“Copy as cURL”查看对应的curl命令写法

Elasticsearch提供了一个丰富的,灵活的查询语言,叫做DSL.Domain-specific language(DSL)使用特定的JSON请求。

查看查询结果
[object Object][object Object]<div class="save_code tracking-ad" data-mod="popu_249"></div>
默认情况下，Elasticsearch根据匹配结果的relevance score进行排序，表示匹配程度。可以看到第二个匹配结果只包含rock也被显示出来。
如果想要完全匹配查询条件，可以使用短语搜索phrase search
使用match_phrase进行条件匹配
