Resources holds two things: what MESO has generated for you, and what you have uploaded yourself.

​
Generated resources

Everything you save from the resource wizard collects here. You can reopen a resource to edit it, and print or export it for class.

​
Documents you upload

You can upload your own material — schemes of work, past papers, notes — and MESO reads it so it can draw on it later.

​
What you can upload

There is a length limit of roughly 400,000 characters per document. That is far longer than any scheme of work or past paper, but it will stop an entire textbook.

​
What happens after upload

The file is stored, its text is extracted, and it is indexed so it can be searched. A document moves through pending → processing → completed, or failed if the text could not be read.
A scanned PDF with no text layer will extract nothing — the file uploads fine and comes back empty. If a document seems to be ignored, check whether it is a scan rather than a real PDF.

​
How search works here

Retrieval over your uploaded documents is full-text search, not semantic search. It matches on the words that are actually in the document.In practice: use the terminology your document uses. Searching for a concept in different words than the document uses will not find it, in the way a meaning-based search would.

​
Privacy

Uploaded documents are private to you. An administrator cannot read them — see Roles and visibility. The same rule applies as everywhere else in MESO: do not upload anything containing identifiable student data.
