…ing totalHits assertion logic (#15807) (#16434)

- Updated the test to account for Lucene's behavior where `IndexSearcher.search()` may return `GREATER_THAN_OR_EQUAL_TO` for totalHits when the number of matches exceeds 1000.
- Added logic to check if `totalHits.relation` is `EQUAL_TO`. If so, assert that the count is exactly 11000. Otherwise, ensure the count is at least 11000 and within the allowed upper limit (`maxHits`).
- This change prevents intermittent test failures caused by Lucene’s performance optimizations.
