Google search: Define what to search in website title vs. body?

When Google searching:

Is there a way to specify what to search in website titles vs. website bodies?

• Include or exclude certain things in the title.
• Include or exclude certain things in the body.

Is there a way to do that?

Here's a hypothetical scenario:

I want to find things that are similar to x, but not the same as x. There are probablywebsites that have lists of things that are similar to x. Or atleast websites that indirectly mention x, which might be helpful.

If I google the word x, I'll just get pages that are 100% about x,which isn't what I want. And when I google the category that I'mthinking of, I get crappy/generic results.

I'd rather google for pages where y is in the title of the webpage (and possibly excludex from the title), but also search wherethe page body contains x. (If the page contains x, then I'll knowthe website is good.)
