For what it's worth, I'm loving my NOOK Color. And the apps for Mac and PC are searchable.
>Christopher: Initial Question/Comment: Is there a way to search the text of a book on my new Nook Color? For example, if I wanted to find every instance of the word "voluminous" in a novel I'm reading?

Michael: Thank you for joining Barnes and Noble Digital Chat Support. One moment while I review your concern. 10:55:21 : Michael: I understand you want to know if there's a built in dictionary on the NOOK Color. Is that correct?
Michael: I understand you want to know if there's a built in dictionary on the NOOK Color. Is that correct? 10:56:01 : 
Christopher: No, not exactly. I want to be able to search for terms within the text of books. Like if I was reading "Zen and the Art of Motorcycle Maintenance" and wanted to jump through and find every instance of the word "tire."
Christopher: No, not exactly. I want to be able to search for terms within the text of books. Like if I was reading "Zen and the Art of Motorcycle Maintenance" and wanted to jump through and find every instance of the word "tire." 10:57:01 : Michael: One moment please.
Michael: One moment please. 10:57:51 : Michael: Just tap and hold the word and there is an option for the dictionary.
Michael: Just tap and hold the word and there is an option for the dictionary. 10:58:37 : Christopher: Right, that's fine, but I don't need a dictionary. That's not what I'm asking about. I'm asking if the text is searchable for particular terms.
Christopher: Right, that's fine, but I don't need a dictionary. That's not what I'm asking about. I'm asking if the text is searchable for particular terms. 10:59:00 : Christopher: Which it is, by the way, on the Nook applications for PC and Mac.

Michael: I see. You are not using the NOOK device, correct? 11:00:39 : Christopher: No, I AM using a Nook device, the NOOK Color. Just bought it the day before yesterday. But I'd already been reading NOOK books via my computers, and want to find out if the search functionality is also present on the NOOK device. And by search, I don't mean search Web or Library, I mean search WITHIN the text of books.

Michael: Do you mean when you look up for word, the device will give you a list of pages where the word is located? 11:06:27 : Christopher: Yes!
Christopher: Yes! 11:06:37 : Christopher: That's what I want anyway.

Christopher: Aha. Thanks, then. Can you answer a question about the NOOK Application for Macintosh? 11:08:31 : Michael: It is also not available on NOOK for Mac.
Michael: It is also not available on NOOK for Mac. 11:10:27 : Christopher: Um, okay. I have a question about whether there are any known problems with the bookmarking feature in NOOK for Mac under OS X Version 10.7. I can't seem to make them work, and under the bookmarking tab I just get a string of text that says "undefinedundefinedundefinedundefined."
