Protecting a searchable repository containing a document locator when a user searches the repository for the document locator, by replacing the document locator with a unique time-sensitive key. The document locator may be a uniform resource locator, or URL. A user search request is intercepted, each URL in the original search result is extracted and replaced with a key, and the altered result returned to the user. When the user selects the key from the search result within the expiration interval, the associated URL and document are able to be retrieved.
