A method of enabling users to perform a search using a search request form. The search request form has coded data indicative of an identity of the search request form and of a plurality of reference points, with some of the coded data being coincident with a search field. In use, the computer system receives indicating data from a sensing device, which is generated when the sensing device is moved within the search field. The indicating data is indicative of the identity of the search request form, movement of the sensing device within the search field and, an identifier stored in a store within the sensing device. The computer system determines the movement of the sensing device within the search field and uses this to perform the search, with the results being provided to the user using the identifier.
