Ennovation and Malcolm are right - search engines will see the entire text, as long as the JS is just being used for show/hide (users without JS enabled will see the same thing).

As long as there is an option to show the text (i.e. it's not completely hidden from users), and the text itself isn't keyword-stuffed or spammy, I can't see a reason why search engines would consider it spam.

Hi Todd,

Using the Pragma no-cache tag means that no cached content from that page will be used when a user next accesses the page; the request will go back to the origin server instead.  It's useful when you have a frequently-updated page that you don't want users to end up seeing older versions of.  It's generally considered to be a bit of an outdated tag - you may want to explore using your HTTP headers to expire content instead - but won't hurt you with the search engines (or prevent the Cached version of your page from showing up in the SERPs).  Hope that helps!
