Hi Grant, For Solr, we're planning to host a benchmarking suite (based on [0]). Wikipedia used to publish query logs [1], which would prove very helpful here. However, they withdrew those files and never published them.
Can you please help? Thanks, Ishan [0] - https://github.com/thesearchstack/solr-bench [1] - https://blog.wikimedia.org/2012/09/19/what-are-readers-looking-for-wikipedia-search-data-now-available/
