Your clone does not know something you uploaded
Why material you added is not coming back, and how to fix it.
You added the document, you asked about it, and your clone said it does not know. Usually one of these.
1. It is still processing
New material has to be processed before it can be used. Large files take longer. Wait a few minutes and try again.
2. The question does not match the wording
Your clone finds material by meaning, not by keyword, but it still needs some overlap. If your document says "client intake sequence" and you ask about "onboarding", it may not connect them.
Fix it by adding a Q&A entry using the words people actually use. This is the most reliable repair, because you control both sides.
3. It is buried in a long document
One fact in a 300 page book competes with everything else in that book. Pull the important part out into its own Text or Q&A source.
4. The file did not contain text
A scanned PDF is a picture of words, not words. If a PDF was scanned or photographed, nothing was extracted. Convert it to real text first, or paste the content in as Text.
5. The guardrail is doing its job
If Only answer from my material is on and the material genuinely is not there, refusing is correct behaviour. Check the source is actually listed on the Knowledge step before assuming a bug.
