Are citations in PhD theses indexed by Google Scholar? I've recently seen a few PhD theses that cite work by our lab, but these citations don't seem to be included in Google Scholar despite the fact that the theses themselves are listed as a publication by the authors. Are these citations excluded? If so, why?
My own PhD thesis has been indexed, but the citations in it haven't, while the citations in other theses published at the same time have been indexed long ago.

I suspect the reason of this is the fancy cover page of my thesis, which doesn't match the document format expected by Google Scholar. For instance, the title should usually be the first line of text in the document.
