1. A method in a computer system for creating a searchable word index of a scanned document, the method comprising: generating a first interpretation of a word at a given location within the scanned document using a first recognition engine; generating a second interpretation of the word using a second recognition engine, wherein the second interpretation is different from the first interpretation; storing a first word node in the searchable word index associating the first interpretation of the word and the location of the word within the scanned document; and storing a second word node in the searchable word index associating the second interpretation of the word and the location of the word within the scanned document.
