No handler for type [text] declared on field [content]

 

Install

1.compile

checkout ik version respective to your elasticsearch version

git checkout tags/{version}

mvn package

copy and unzip target/releases/elasticsearch-analysis-ik-{version}.zip to your-es-root/plugins/ik

2.restart elasticsearch

Tips:

ik_max_word: 会将文本做最细粒度的拆分,比如会将“中华人民共和国国歌”拆分为“中华人民共和国,中华人民,中华,华人,人民共和国,人民,人,民,共和国,共和,和,国国,国歌”,会穷尽各种可能的组合;

ik_smart: 会做最粗粒度的拆分,比如会将“中华人民共和国国歌”拆分为“中华人民共和国,国歌”。

Quick Example

1.create a index

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

2.create a mapping

curl -XPOST http://localhost:9200/index/fulltext/_mapping -d{    "fulltext": {             "_all": {            "analyzer": "ik_max_word",            "search_analyzer": "ik_max_word",            "term_vector": "no",            "store": "false"        },        "properties": {            "content": {                "type": "text",                "analyzer": "ik_max_word",                "search_analyzer": "ik_max_word",                "include_in_all": "true",                "boost": 8            }        }    }}

上面这个rest请求在2.3.4版本的es服务器上会执行失败,原因是es 2.3.4上面还没有text这种类型,"type":"text" 改为 "type":"String"即可
