How to check the log and performance of warmer?

Elastic Stack Elasticsearch
1

Hi All,

I am new to elasticsearch. I have added a warmer for my index. But I cannot
see any log and performance improvement after using the warmer.
All information I can find are from the api( ref :
http://www.elasticsearch.org/guide/reference/api/admin-indices-warmers/ ).

I add the warmer by
curl -XPUT localhost:9200/test/_warmer/warmer_1 -d '{
"query" : {
"match_all" : {}
},
"facets" : {
"facet_1" : {
"terms" : {
"field" : "field"
}
}
}
}'

I can see the warmer by
curl -XGET localhost:9200/test/_warmer/warmer_1

I start doing the indexing on the index test with field 'field'. the doc
size is 10k and the index size is 100mb.
I do search after the indexing and study the time taken for the first
search. But I finid that It is the same as the time taken from another
index(same data) without warmer.
Also, there is no log for the warm up part.

May I know in what condition the warmer search is performed?

  1. after indexing new doc?
  2. after re-indexing the same doc?
  3. manual call the index refresh?

How can I check is the warmer helping my search?

Thanks All.
