Does anyone know how to view or expand the snippet of a google search result? One can lengthen their query to include what they know comes after or before an ellipsis, but even if one remembers, eventually the snippet stops expanding.

I'm trying to access a page of a site that has been deleted from the site's servers (apparently), but when the right query is entered into google, text from the absent page is displayed in a snippet. The whole text appears to be somewhere - either hidden on the site or in google's database - as modifying the query changes the snippet (but not to the critical part of the text which I've forgotten), but webcache.googleusercontent.com hasn't saved the page url, and a search of site:webcache,googleusercontent.com/search?q=cache:[site] yields no results.

It's not just this particular case that bothers me; I've experienced this before and want to know how to access the whole of the snippet text. The Wayback machine does not creep extensively enough to solve this problem.
If you require specific site information please pm me. Thank you.
