I went to the Search option today and popped in a couple of names of authors - Robert B. Parker (Jessie Stone) and J. D. Robb (In Death series) and it only brought up 6 items. Did this a couple of times thinking I'd done something. Finally sent a message to TPTB and they said they are looking into it and hope to have it fixed soon. I even popped in the name of one of Parker's books, and it brought up 6 items, and none were the book I was searching for, so if you find that you're not finding what you're looking for, it's not you. 

They seem to have fixed it, as now I have several pages of books for J. D. Robb I can search through. Pat

At the FOL used bookstore where I volunteer we have tons of JD Robb titles!  We get sick of seeing them.
