Google-search – How to make Google Search default for all words with “allintext:”

I can't help you with the list of any “top” rating, but!

This tool by Google gives you ability to see the amount of searches for any phrase. The default setting is so-called “broad” match data — so, if you key in recipe, you will see amount of searches for all queries that have “recipe” in them, in any form.

It won't give you a rating, but it will show you the absolute amount of monthly searches, possibly filtered by language and/or country.

If you are using the Firefox Google search toolbar, I am not sure how to permanently make that change.

But if you are using the search field (the one that's to the right of the address bar by default), you can write your own search plugin fairly easily.

Following the example on that page, you would put the QDR parameter (as described in another answer) in like so:

<search 
 name="Google: Past Year"
 method="GET"
 action="http://www.google.com/search"
 queryCharset="utf-8"
> 

  <input name="q" user>
  <input name="qdr" value="y">
</search>
