Suggestion for \cite in Emacs with AUCTeX

Question

I would like to know how can I get the suggestion when I do a \\cite in Emacs-AUCTeX. The minibuffer tells me when I do C-c [ that:

No valid bibliography

Answer 1

The variable reftex-default-bibliography is what defines the default bibliography to use. I don't do much with mult-file documents, do you have reftex-plug-into-AUCTeX turned on?
