分词器

测试ik切词：http://host_name_xx:port_yyy/qa_pair/_analyze?analyzer=ik&pretty=true&text=我是中国人"

综上，同样是对“这是一个对分词器的测试”进行分词，不同的分词器分词结果不同：
ik_max_word：这是/一个/一/个/对分/分词器/分词/词/器/测试
ik_smart：这是/一个/分词器/测试
standard：这/是/一/个/对/分/词/器/的/测/试

{"analyzer":"ik_max_word","text":"这是一个分词器"}

/person/_mapping

index 属性控制怎样索引字符串。它可以是下面三个值：

analyzed

首先分析字符串，然后索引它。换句话说，以全文索引这个域。

not_analyzed

  索引这个域，所以它能够被搜索，但索引的是精确值。不会对它进行分析。

no

不索引这个域。这个域不会被搜索到。

string 域 index 属性默认是 analyzed 。如果我们想映射这个字段为一个精确值，我们需要设置它为 not_analyzed ：

{
    "tag": {
        "type":     "string",
        "index":    "not_analyzed"
    }
}

虽然写入数据时Elasticsearch会自动的添加映射进行处理，但是删除数据并不会删除数据的映射

#curl -XDELETE 'http://localhost:9200/logstash-2016.01.01/syslog'                  删除了syslog下面的全部数据，但是syslog的映射还在

删除映射的命令:

#curl -XDELETE 'http://localhost:9200/logstash-2016.01.01/_mapping'

删除索引的话映射也会删除

#curl -XDELETE 'http://localhost:9200/logstash-2016.01.01'
