Yep. ElasticSearch is actually quite slow, as text engines go. It seems designed to scale, rather than provide single-machine performance. Even so we are seeing very slow queries on our 8-node cluster, even for relatively simple queries and small datasets. It seems very sensitive to the result set size (ie., the maximum item number set in the query). A limit of 50 might take 500ms (which is slow but acceptable in our case) whereas 1000 results might take 3-4 seconds. The indexes are all in OS cache so disk performance is not the bottleneck.
