如何使elasticsearch文件工作？

Question

我安装了debian包

我能够使用curl推送数据:

curl -XPUT 'http://mybox:9200/blog/user/dilbert' -d '{
  "name": "Dilbert Brown"
}'

并获取它

curl -XGET 'http://mybox:9200/blog/user/dilbert'

结果:

{
  "_index": "blog",
  "_type": "user",
  "_id": "dilbert",
  "_version": 2,
  "exists": true,
  "_source": {
    "name": "Dilbert Brown"
  }
}

并找到它

curl -XGET 'http://mybox:9200/blog/user/_search?q=name:Dilbert+Brown&pretty=True'

我想用5秒5秒的ttl推送相同的记录,并在尝试获取此条目时获得404 http状态代码.此条目也不应在搜索结果中可见.

注意:我尝试了各种搜索配置组合

• http://www.elasticsearch.org/guide/reference/mapping/ttl-field/
• http://www.elasticsearch.org/guide/reference/api/index_/
• http://elasticsearch-users.115913.n3.nabble.com/TTL-in-elastic-search-is-not-working-td4034844.html

他们都没有帮助我.

有人可以提到一个简单的步骤序列,让我实现目标结果吗？

Answer 1

这对我有用:

curl -XPUT 'http://localhost:9200/blog/user/_mapping' -d '{"user": {"_ttl": {"enabled": true, "default": 5000}}}'

curl -XPUT 'http://localhost:9200/blog/user/phb' -d '{"name" : "Pointy-Haired Boss"}'

sleep 60  # this is the default deletion interval for the expired documents

curl -XGET http://localhost:9200/blog/user/phb  # 404

Answer 2

@bereal是对的.

要使ttl工作,您必须首先在映射中启用它(默认情况下,它已被禁用),然后在索引文档时设置TTL值.

curl -XPUT 'mybox:9200/blog/user/_mapping?pretty' -d '{
  "user": {
     "_ttl": {"enabled": true}
}'

curl -XPUT 'mybox:9200/blog/user/dilbert' -d '{ "name" : "Dilbert Brown", "_ttl": "3m"}'

curl -XGET 'mybox:9200/blog/user/dilbert?pretty'
