Why is full text search not finding all instances of my search term in a book or in the collection?

BHL’s full text search is searching the generally uncorrected text derived through Optical Character Recognition (OCR) for your term. Since this OCR is automatically-generated and uncorrected, it may be incomplete or have errors that prevent the search engine from locating all instances of your term.
