Why aren't all bugs shown? Why isn't the bug I reported showing up?

Bug report information is available for releases beginning with Release 14 SP2. Information is not available for all bugs, known or unknown, including bugs in prior releases. If you feel your bug should appear in this table, contact technical support and ask that your bug be nominated as a bug report.
Does this interface include information on enhancement requests?

How are the bugs sorted in the table view?
Bugs are sorted first by the date modified. You can sort them by bug ID or search relevance.
How can I search for individual bugs?
