The "Case-sensitive" and "Search-type" functions are optional - if you leave them out, the search will default to no case-sensitivity and exact search, (meaning a search for "TrIPod" will find "Tripod") and exact search (in which a search for "Tripod homepages" will only produce exact matches). A 'Fuzzy' search will call up results with a matching prefix, so if you search for 'the', your search will also find "then" and "thereabouts."
