An exact match of the signature of text to be located that is nearest to the expected location of the text to be located is sought. If an exact match of the signature is not found at the expected location, a close match to the signature, that is nearest to the expected location, is sought. If the exact match is found, the location of the exact match is identified as the location of the text being searched for.
