Does Google search from HTML or text page?

Have I got this wrong?

Hi

Does Google search on HTML or only text that is displayed to the user.

I only ask because I'm sure last month I could search on keywords - but I have just tested my site again and the only search results come from either the Title or text that is displayed.

Thanks - Stephen
