Why are there two search functions?

Loopyguy.com offers two distinctly different search engines. Each search engine actually works differently, instead of disabling the default search function, another search function was added.

Search box: The search box provides a "fuzzy search" meaning search results do not have to match exactly the search criteria. The entire site is indexed and each 'word' is broken up into three digit pieces, each piece is a portion of a search result. The word apple is broken into "app", "ppl", and "ple". When you search on epple, you'll still get "apple" in the search result.

Search menu item: Within the main menu you'll see "Search". This is the default search for the site, partial words are not indexed, so you would have to match an exact word to get a search result, although you could use the Advanced Search to narrow your search result to a particular criteria, which the "fuzzy search" does not offer.
