Because such a search would return an astronomical number of results. Plus it may return pages that reported "803112" hits when the spider visited the site, or perhaps that had a phone number of 303-555-8051.

But the main reason is so many results would be returned that it would not be a useful search, especially in our field where searching for 8051 could almost return every page in the search database.

Trying refining your search with additional non-numeric search terms.
