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/](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.
