There is a known limitation in the browser-based domain search feature that affects very large domains. When a domain contains over 10,000 breached email addresses, the search results are trimmed to the first 10,000 records. Filtering by the latest breach then only applies the filter to that list of 10,000, which may lead to unexpected results. A permanent fix for this is presently on the backlog.
In the interim, there are three alternative searches that will return all results:
- Using the JSON link at the top of the domain search page
- Using the Excel link at the top of the domain search page
- Searching the domain using the API
