I've never been very impressed with FindMyPast's 1911 transcriptions, or their search utiility. Quite often I've searched for a name using Christian, Middle and Surname on the Advanced Search, and found nothing. Then I've turned to the normal search, and searched for just Christian name and surname, and have been deluged with matches, including the one with the middle name that the Advanced Search was unable to find ! Similarly, if I search for my own street name in "Search by Address", it doesn't come up, but when I type in the name of the town, it lists the streets, including the one that it couldn't find before
