我有以下问题: 我有一个3000万个文档的索引,映射如下:
curl -XPUT localhost:8080/xxxxx/yyyyy/_mapping?pretty=true -d '{"xxxxx":{"_id":{"type":"string","index":"not_analyzed"},"properties":{"content":
{"type":"string","store":"no"},"title":{"type":"string","index":"no"},"created_date":{"type":"integer","index":"not_analyzed"},"url":
{"type":"string","index":"not_analyzed"},"author":{"type":"string","index":"no"},"author_url":{"type":"string","index":"no"},"domain":
{"type":"string","index":"not_analyzed"},"lang":{"type":"string","index":"no"}}}}'
未在设置中选择Tokenizer,因此请应用标准。 我想请求“facets”在字段“content”中创建排名链接(url)。不幸的是我无法做到这一点,因为标准的tokenizer会将链接(url)分享到碎片。 题: 没有重新索引的现有索引是否可以更改标记生成器,以便添加到索引的新文档处理新的标记生成器(uax_url_email),旧文档保持不变。
我试过了:
curl -XPUT localhost:8080/xxxxx -d '{
"settings" : {
"index": {
"analysis" :{
"analyzer": {
"default": {
"type" : "custom",
"tokenizer" : "uax_url_email",
"filter" : "lowercase"
}
}
}
}
}
}
'
但是我收到一个错误:
{"error": "IndexAlreadyExistsException [[xxxxx] Already exists]", "status": 400}
有没有其他方法可以不使用查询“facets”重新索引来创建排名链接(网址)?
提前感谢您的任何帮助
答案 0 :(得分:1)
对于现有索引“xxxxx”
,请尝试下一步curl -XPUT localhost:8080/xxxxx/_settings -d '{
"analysis" :{
"analyzer": {
"default": {
"type" : "custom",
"tokenizer" : "uax_url_email",
"filter" : "lowercase"
}
}
}
}
确保您的elasticsearch端口为8080,默认为9200
