The metadata in the search results is arranged in a tabular view which is embedded in the display of search results and rendered invisible until selected by the user. Reports can be constructed from an identifier each returned record set for presenting, analyzing and modifying the data, and for generating further reports.

Ordered binder document sections having different file formats stored within a binder file. The binder file maintains the order of binder document sections and the native file format of each section. The ordered sections can be viewed and edited through a viewport of a frame displayed by a binder program module. By selecting graphical images displayed in a selection area of the frame the content of a binder document section can be viewed and edited without viewing the content of other binder document sections. The graphical images can be icons or graphical images derived from the content of sections called thumbnail images. A thumbnail image can be derived from either the first page or from multiple pages of an individual section. The binder program module can also dispatch the underlying application program modules that created each binder document section to print, spell check, and grammar check the binder document sections as a single data processing task. In this manner, selected sections of a binder document can be printed as a single consecutively printed document without having other print jobs interrupting or intervening between printed sections of the binder document.

A fuel vapor handling apparatus supplies a purging air to a canister by using a purge pump and purges fuel desorbed from the canister into an intake pipe. A controller intermittently operates the purge so that the canister internal temperature recovers from a reduced level caused by the latent heat of vaporization of fuel during an operating period of the purge pump. Therefore, desorption of fuel from the canister during an operating period is facilitated. Since the actual operating time of the purge pump is reduced, the life of a motor that is a power unit of the purge pump becomes longer.
