I am just curious, I know a search on 5 shards take 5 Java threads, but if each shard have 10 segments:
- Each segments are searched synchronously ? (mean the more segments the longer is the search)
- Each segments are search in parallel ?
(I search arguments to recommend elasticsearch, from Q&A from "The Great Search Engine Debate - Elasticsearch, Solr or Vespa?" Meetup | Vespa Blog ^^)
