This is a great idea! I think your best bet is to look for databases of primary sources. There are a number of paid searchable online databases of primary sources. Many of them are cost-prohibitive or unavailable to individuals, so you might need to find a friend who access to them through a university.
This unfortunately will only work for areas and time periods where you speak the language, but most written history is put in context with the past and future which makes it a non-starter.

Do you know the names or URLs of any of those databases in particular?
