when I do site:search with the url's of single pages they do appear.
I don't know about a site:search with an exact phrase from a page. Could I not put this single phrase into the search bar?
In any case - in both cases google says 'not found'.
It's odd - because if the site is indexed google should be able to find it. Why not I ask myself and you (I am sure much more knowledgeable people than me)
