Docker安装IK分词器

上文： Win10中Docker安装Elasticsearch

我们需要安装IK分词器
进入容器,会发现此时plugins文件夹下空空如也:

D:\>docker exec -it tensquare_es /bin/bash
root@fe7ebf1c90bf:/usr/share/elasticsearch# cd plugins/
root@fe7ebf1c90bf:/usr/share/elasticsearch/plugins# ls
root@fe7ebf1c90bf:/usr/share/elasticsearch/plugins# exit
exit

1.进入容器

D:\>docker exec -it tensquare_es /bin/bash

2.安装ik插件

root@b9bc5264d13d:/usr/share/elasticsearch# elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v5.6.8/elasticsearch-analysis-ik-5.6.8.zip

由于用的是校园网，刚开始总是报SSL异常的错误，后来更换为自己的手机热点，不再报错，很快就完成了。
当然也可以从别处下载到本地后直接将ik解压cp到plugins目录下

3.重启容器

docker restart myes

IK分词器用法示例：

参考github上ik示例

Quick Example

1.create a index

curl -XPUT http://localhost:9200/index

2.create a mapping

curl -XPOST http://localhost:9200/index/fulltext/_mapping -H 'Content-Type:application/json' -d'
{
        "properties": {
            "content": {
                "type": "text",
                "analyzer": "ik_max_word",
                "search_analyzer": "ik_max_word"
            }
        }

}'

3.index some docs

curl -XPOST http://localhost:9200/index/fulltext/1 -H 'Content-Type:application/json' -d'
{"content":"美国留给伊拉克的是个烂摊子吗"}
'

curl -XPOST http://localhost:9200/index/fulltext/2 -H 'Content-Type:application/json' -d'
{"content":"公安部：各地校车将享最高路权"}
'

curl -XPOST http://localhost:9200/index/fulltext/3 -H 'Content-Type:application/json' -d'
{"content":"中韩渔警冲突调查：韩警平均每天扣1艘中国渔船"}
'

curl -XPOST http://localhost:9200/index/fulltext/4 -H 'Content-Type:application/json' -d'
{"content":"中国驻洛杉矶领事馆遭亚裔男子枪击 嫌犯已自首"}
'

4.query with highlighting

curl -XPOST http://localhost:9200/index/fulltext/_search  -H 'Content-Type:application/json' -d'
{
    "query" : { "match" : { "content" : "中国" }},
    "highlight" : {
        "pre_tags" : ["<tag1>", "<tag2>"],
        "post_tags" : ["</tag1>", "</tag2>"],
        "fields" : {
            "content" : {}
        }
    }
}
'

Result

{
    "took": 14,
    "timed_out": false,
    "_shards": {
        "total": 5,
        "successful": 5,
        "failed": 0
    },
    "hits": {
        "total": 2,
        "max_score": 2,
        "hits": [
            {
                "_index": "index",
                "_type": "fulltext",
                "_id": "4",
                "_score": 2,
                "_source": {
                    "content": "中国驻洛杉矶领事馆遭亚裔男子枪击 嫌犯已自首"
                },
                "highlight": {
                    "content": [
                        "<tag1>中国</tag1>驻洛杉矶领事馆遭亚裔男子枪击 嫌犯已自首 "
                    ]
                }
            },
            {
                "_index": "index",
                "_type": "fulltext",
                "_id": "3",
                "_score": 2,
                "_source": {
                    "content": "中韩渔警冲突调查：韩警平均每天扣1艘中国渔船"
                },
                "highlight": {
                    "content": [
                        "均每天扣1艘<tag1>中国</tag1>渔船 "
                    ]
                }
            }
        ]
    }
}

发现分词器已生效了。
