Executing test

A search target index is rewritten by ab_rt parameter. In the above case, if ab_rt parameter is 0-9, target index is rewritten sample-index-a.

Search sample-index

curl -XPOST localhost:9200/sample-index/doc/_search?q=*:*

Search sample-index-a (ab_rt is 0-9)

curl -XPOST localhost:9200/sample-index/doc/_search?q=*:*&ab_rt=5&hash_rt=false

Search sample-index-b (ab_rt is 10-29)

curl -XPOST localhost:9200/sample-index/doc/_search?q=*:*&ab_rt=20&hash_rt=false

If you set "true" to hash_rt parameter, ab_rt parameter value is converted to hashCode.(default)
