Documentation search should be selected and tuned around the queries users fail to resolve, not around a feature checklist from vendors. Search is most valuable when readers know a term or symptom but not where the information lives.

Practice
A practical way to separate harmless old pages from documentation debt that creates support work, failed tasks and release risk. Age alone does not create debt; user failure and maintenance cost do.

Archive
Many modern documentation patterns began as older hypertext problems: how to split information, name destinations and help readers recover when they get lost. Hypertext gave readers freedom from a linear manual and immediately created orientation problems.

Practice
A documentation tree that works at fifty pages can fail at five hundred. Build navigation around user tasks, content types and durable concepts before the archive becomes a map of the org chart. Small documentation sets can survive almost any navigation scheme.
