1、改變ES默認深度分頁的index.max_result_window 最大窗口值
curl -XPUT http://127.0.0.1:9200/my_index/_settings -d '
{
"index" : {
"max_result_window" : 500000
}
}'
2、磁盤閾值
curl -XPUT http://127.0.0.1:9200/_cluster/settings -d '
{
"transient":{
"cluster.routing.allocation.disk.threshold_enabled":true,
"cluster.routing.allocation.disk.watermark.low":"75%",
"cluster.routing.allocation.disk.watermark.high":"90gb",
"cluster.info.update.interval":"30s"
}
}'
3、修改副本數量
curl -XPUT http://127.0.0.1:9200/index/_settings -d '
{
"index":{
"number_of_replicas":0
}
}'
4、刪除索引
curl -XDELETE http://127.0.0.1:9200/index-`date -d "1 week ago" + '%Y-&m-%d'`
5、aggs多字段聚合
curl -XGET 'http://localhost:9200/index/field/_search?pretty' -d '{
"size":0,
"aggs":{
"tag1":{
"terms":{
"field":"keyword1",
"size":num1
},
"aggs":{
"tag2":{
"terms":{
"field":"keyword2",
"size":num2
},
"aggs":{
"tag3":{
"avg":{
"field":"keyword3"
}
}
}
}
}
}
}
}'
