Explanations / Notes:

Input values for any or all of the categories to narrow things down. _ is the wildcard for a single character, % is the wildcard for an indefinite number of characters.

Examples:
Games released in 2000? ReleaseDate: 2000-%
Games released in March? ReleaseDate: %-03-%
Games released on the 10th? ReleaseDate: %-10
Mario games? TitleEnglish: %Mario%
Games with titles ending in DS? TitleEnglish: % DS
Games with a single digit ID? GameID: _
Games released by Square or Square Enix? Publisher: Square%

If you enter NONE for the later release date or price option, it will treat the first one as the only. Why would you want to do this? Though setting a time range is usually more useful, it doesn't completely allow everything the older one-input method allowed, such as the "Games released in March" and "Games released on the 10th" possibilities listed among the examples above.

Order by allows you to order the results as you wish. It's possible to order by Publisher, Platform, ReleaseDate, GameID, TitleEnglish, TitleJapanese, LaunchPrice, and SalesLTD. After each option put ASC for ascending order or DESC for descending order. Commas between first rule, second rule, and so on.

Examples:
Order by platform alphabetically, then publishers alphabetically, then sales from greatest to least: Platform ASC, Publisher ASC, SalesLTD DESC
Order from most expensive to cheapest, then from most recent to oldest: LaunchPrice DESC, ReleaseDate DESC
Order by release date from earliest to most recent, then by platform, then by publisher, and if there's still any ambiguity go by the Game ID: ReleaseDate ASC, Platform ASC, Publisher ASC, GameID ASC (the default)
