LOL, now I'm getting confused.
Okay, let me try to answer your questions...
The first thing is, I think you're confused. When a user searches for the questions, the page found is not a static page, it's a dynamic page generate by the users; thus, only valid for that session and moreover, it woulnd't have any links pointing to it. So there would be no problem with duplicate content.
Any methods that has been mentioned works fine with UX and SEO. Either the AJAX slideout method, the search or a static display. Test/Marie, I'm sorry if I'm confusing you guys - all these different methods of the FAQ require different methods of programming and user interaction - so just because one method might be poor for SEO/etc does not mean it reflect all and vice versa. Different methods have different drawbacks and advantages. Which is (correct me if I'm wrong) what the OP is entertaining - different situations and how Google would react. If my count is up, I think we've covered 3 variations to this problem with different possible solutions.
Maybe I'm just going on too much and confusing myself. It's very well possible.
Test, when you mention scanning AJAX that was to my first reference to the original question based on the FAQ's as they currently sit, not in our hypothetical searching/ask question situation that just recently came up. The quote you took from me was my direct response to the initial question - sorry if that's confusion with the different possible solutions for this.
I hope that unconfused you, bud.
Are you using a custom coded site or a CMS such as WordPress or Joomla? If the latter, there may be some existing plugins that could help and save time?
That's a pretty good idea. Like an autocomplete. Adding fuel to the complication fire ;-)
