## The problem
Recurring searches with the same request for dense_vector exhibit consistency issues: identical dense_vector queries return different results across runs.
## The fix
If identical dense_vector queries return different results across runs, the inconsistency is in the vector search layer, not your query or index. It was fixed upstream by bumping Elasticsearch to Lucene 10.3 (PR #133980). Fix: upgrade to an Elasticsearch version that includes the Lucene 10.3 bump. Don't waste time tuning the query, it's a search-engine bug.
