Issue Type: Task Affects Versions: 6.0.0.Beta8 Assignee: Unassigned Components: backend-lucene Created: 11/Jun/2020 03:14 AM Fix Versions: 6.0.0.Beta-backlog-low-priority Priority: Major Reporter: Fabio Massimo Ercoli ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%3A097eae70-1c75-4c16-ab75-ab9600f8e584 )

Instead of allocating such arrays, we could introduce an incremental allocation behind the hood.
E.g.: we'd execute the query once to retrieve the top 100, and if there is more, we'd do it again with 200, then 400, then 800, and so on.
