Search is part of the interface.
Especially for a thinking archive.
The page someone lands on matters.
But so does what they can find.
A useful public notebook should make the recurring patterns searchable.
Not just by exact title.
By topic.
By question.
By source.
By old writing.
By current lens.
By the kind of conversation someone wants to have.
Search is not only a box.
It is the shape of the metadata underneath the site.
