elasticsearch 设置mapping时出错

Question

在使用官方文档案例
PUT /my_store
{
"mappings" : {
"products" : {
"properties" : {
"productID" : {
"type" : "string",
"index":"not_analyzed"
}
}
}
}
}
时报错：
{
"error": {
"root_cause": [
{
"type": "mapper_parsing_exception",
"reason": "No handler for type [string] declared on field [productID]"
}
],
"type": "mapper_parsing_exception",
"reason": "Failed to parse mapping [products]: No handler for type [string] declared on field [productID]",
"caused_by": {
"type": "mapper_parsing_exception",
"reason": "No handler for type [string] declared on field [productID]"
}
},
"status": 400
}

Answer 1

看你下载的ES是哪个版本，5.x以上已经没有string类型。如果需要分词的话使用text，不需要分词使用keyword。
具体可以参考这篇博文：http://blog.csdn.net/paditang/article/details/78949233
另：官方中文文档比较滞后，建议查看英文文档
