es-ikES上使用IK中文分詞器

IK中文分詞器在Elasticsearch上的使用。原生IK中文分詞是從文件系統(tǒng)中讀取詞典，es-ik本身可擴(kuò)展成從不同的源讀取詞典。目前提供從sqlite3數(shù)據(jù)庫中讀取。es-ik-plugin-sqlite3使用方法：

1. 在elasticsearch.yml中設(shè)置你的sqlite3詞典的位置：

ik_analysis_db_path: /opt/ik/dictionary.db

我提供了默認(rèn)的詞典：https://github.com/zacker330/es-ik-sqlite3-dictionary

2. 安裝（目前是1.0.1版本）

./bin/plugin -i ik-analysis -u https://github.com/zacker330/es-ik-plugin-sqlite3-release/raw/master/es-ik-sqlite3-1.0.1.zip

3. 現(xiàn)在可以測(cè)試了：

    1. 創(chuàng)建index

curl -X PUT -H "Cache-Control: no-cache" -d '{
    "settings":{
        "index":{
            "number_of_shards":1,
            "number_of_replicas": 1
        }
    }
}' 'http://localhost:9200/songs/'

      2. 創(chuàng)建map:

curl -X PUT -H "Cache-Control: no-cache" -d '{
        "song": {
            "_source": {"enabled": true},
            "_all": {
                "indexAnalyzer": "ik_analysis",
                "searchAnalyzer": "ik_analysis",
                "term_vector": "no",
                "store": "true"
            },
            "properties":{
                "title":{
                    "type": "string",
                    "store": "yes",
                    "indexAnalyzer": "ik_analysis",
                    "searchAnalyzer": "ik_analysis",
                    "include_in_all": "true"
                }
            }

        }
}
    ' 'http://localhost:9200/songs/_mapping/song'

       3.

curl -X POST  -d '林夕為我們作詞' 'http://localhost:9200/songs/_analyze?analyzer=ik_analysis'

response:
{"tokens":[{"token":"林夕","start_offset":0,"end_offset":2,"type":"CN_WORD","position":1},{"token":"作詞","start_offset":5,"end_offset":7,"type":"CN_WORD","position":2}]}
