Searching

How search works

Search matches the words in your question. The same question always gives the same answer.

Word matching, not AI

AETHER-33 ranks memories by how well their words match your question, using a long-established search formula called BM25 (the same family of ranking that classic search engines use). Rare words count for more than common ones, and short exact matches rank above long rambling ones.

Why this choice

Narrowing a search

What it cannot do

It will not find a match that shares no words with your question: “car” does not find “automobile.” If you need meaning-based search, put a vector search in front and keep AETHER-33 as the trustworthy record of what was actually written.

AETHER-33 is a product over CAIN-42's governed-memory stack, not a new architecture moat. Memory never carries authority: every response is annotated grants_authority: false. No third-party audit has been performed. Limits · FAQ · what is live now
