The "exact match" parameter is an optional feature in reverse WHOIS searches. When used with keywords, company names, or owner names, it ensures that the search results match the exact terms entered. This helps users find more precise and relevant information by filtering out results that don't perfectly align with the query.
Note:
The "exact match" parameter can only be used with keywords, owner/registrant names, or company names. It is not applicable for email addresses, meaning you cannot use exact match to filter results based on email addresses.
