Jeanne,
The title search is, well, a bit peculiar. What you should have done when getting 'Song of songs' is to click on the link named 'Next entire page' (and maybe repeat this procedure a couple of times) and you would have got the song. This is a general advice when using the title search.

There is nearly nobody in here who has not been fooled by this at least once, so don't think it is your fault. I just tell it so you know why you are puzzled.
