Without a doubt. I'm sure Google have optimised the search for years
and are happy to achieve small percentage improvements.
http://www.google.com/jobs/eng/sw.html lists job openings at Google.
Most require Python in one form or another.
A quote from google themselves (from the python.org web page)
"Python has been an important part of Google since the beginning, and
remains so as the system grows and evolves. Today dozens of Google
engineers use Python, and we're looking for more people with skills in
this language." said Peter Norvig, director of search quality at Google,
Inc.

I have no knowledge on how Google do what they do but I'm thankful
they do it everytime I search their 3 billion indexed web pages and
get a responce time in the low seconds.
In one way or another Python has helped them achieve this.

The other quote I forgot to mention from:
http://www.python.org/community/users.html
"At one point Scott Hassan, one of the founders of Findmail/eGroups (the
company that was later acquired by Yahoo), reported that they had
180,000 lines of Python underlying everything from their 100% dynamic
website to all email delivery, pumping out 200 messages/second on a
single 400 MHz Pentium."
Alot of people "assume" Python is to slow for many tasks.
It's always best not to assume.
OK, sorry everyone, that's enough Python talk for a year or so.

If that is true, that's probably why 90% or more of the people use
Google, as that is a terrible way to index pages. Google cares very
little if at all about meta tags...

1. Google does not use meta tags at all. You can prove this yourself.
Google's ratings (according to Google) are based on the number
and quality of links *to* your website from other sites, and on
very little else.
2. Google (as well as those which do use meta tags) do not search
in "real time". Just check your server logs, you'll see that google,
yahoo, etc. visit once or twice a month to index your pages.
So whatever search engine you use, it's just referencing a database.
I believe Python works just fine for updating this database.
