如何在弹性搜索中设置标记器 [英] How to setup a tokenizer in elasticsearch
问题描述
我无法弄清楚我通过配置文件如何做到这一点。任何人都可以指出我通过配置文件来做到这一点吗?
除此之外,可以通过对索引执行POST来调整索引,同时启动和运行索引?我真的很想了解如何使用这个,谢谢。
编辑/更新:我无法将curl -XPUT或-XPOST运行到localhost:9200,以尝试从我所拥有的一些示例/论坛中调整设置在搜索帮助的时候看到,我得到'没有处理程序的uri []和方法[PUT] / [POST]的结果。
编辑2:更新,做一个索引的XPUT工作,但是我收到一个关于索引已经存在的错误。我知道它存在,我想更新它。
您可以在配置文件中定义映射,但在大多数情况下通过API配置更容易/更灵活。例如,此命令将向索引 test
添加关键字/小写分析器:
$ curl -XPUT localhost:9200 / testindex / -d'
{
settings:{
index:{
analysis:{
analyzer:{
analyzer_keyword:{
tokenizer:keyword,
filter:小写
}
}
}
}
},
mappings:{
test:{
properties:{
title :{
analyzer:analyzer_keyword,
type:string
}
}
}
}
} '
I have an embedded elasticsearch using the elasticsearch-jetty project, and I need to setup to use tokenizers better than the defaults. I want to use the keyword tokenizer.
I can't figure out for the life of me how to do this through the config files. Can anyone point me at a way to do this through config files?
As an aside, is it possible to adjust the index while it's up and running by doing a POST to the index? I'd really like to understand how to use this, thank you.
EDIT/update: I'm having trouble running curl -XPUT or -XPOST to localhost:9200 to try to adjust settings from some of the examples/forums I've seen when searching to help here, I'm getting results of 'No handler for uri [] and method [PUT]/[POST].
EDIT 2: Update, doing XPUT to an index works, but I get an error about "Index already exists". I know it exists, I want to update it.
You can define mappings in the config files, but for most cases it is easier/more flexible to configure through the API. For example, this command will add a keyword/lowercase analyzer to the index test
:
$ curl -XPUT localhost:9200/testindex/ -d '
{
"settings":{
"index":{
"analysis":{
"analyzer":{
"analyzer_keyword":{
"tokenizer":"keyword",
"filter":"lowercase"
}
}
}
}
},
"mappings":{
"test":{
"properties":{
"title":{
"analyzer":"analyzer_keyword",
"type":"string"
}
}
}
}
}'
