"Heavy" queries for elasticsearch

Ηello everyone,

i am looking for queries-searches to do on my elasticsearch cluster to push it to the limits. My goal is to compare the response time by executing the same search while i am adding more nodes to the cluster.
I would like to see the scalability of my cluster and how adding more nodes improves the response time.

Any ideas?

Whatever queries you'd expect users to actually do. In general phrase
queries are more expensive than non-phrase queries. Highlighting is
expensive - more expensive with large number of results returned. Too many
results returned will crash elasticsearch - like millions.

try wild-cards that matches a good number of hits
