By fragment, across the whole fonds
“Projektions” finds “Projektionsapparat”. Search is cumulative: every term added narrows it down, and you choose the scope — the page, the shelfmark, the whole repository.
Two words in the same sentence
“Goerz” near “Berlin”, within fifty characters: proximity is checked against the text itself, not estimated. That’s what tells a mention apart from a coincidence.
Indexed, with their spellings
“Barsy, A. v.” and “A. v. Barsy” are the same person; an OCR typo or a missing umlaut are matched and offered to you for merging — never merged automatically. “Pages about X” answers instantly.
Understood, even when imprecise
The item’s date and dates it mentions are recorded as written. “1925” and “24 March 1925” become comparable: an imprecise date is treated as a range.
Read at the foot of the page
When the volume’s reference is printed on the page, it is read and suggested for the pages that follow. What you enter yourself always takes precedence.
