I use google for my searches. Google is simply the best search engine!

Good things about google:

It uses Page Ranking when it displays search results...
Code:
PageRank relies on the uniquely democratic nature of the web by using its vast link structure as an indicator of an individual page's value. In essence, Google interprets a link from page A to page B as a vote, by page A, for page B. But, Google looks at more than the sheer volume of votes, or links a page receives; it also analyzes the page that casts the vote. Votes cast by pages that are themselves "important" weigh more heavily and help to make other pages "important."

Important, high-quality sites receive a higher PageRank, which Google remembers each time it conducts a search. Of course, important pages mean nothing to you if they don't match your query. So, Google combines PageRank with sophisticated text-matching techniques to find pages that are both important and relevant to your search. Google goes far beyond the number of times a term appears on a page and examines all aspects of the page's content (and the content of the pages linking to it) to determine if it's a good match for your query.
It's alot faster than other search engines

Google covers more than 8 billion URLs

Instead of web page summaries that never change, Google shows an excerpt (or "snippet") of the text that matches your query -- with your search terms in boldface -- right in the search results. This sneak preview gives you a good idea if a page is going to be relevant before you visit it.

You can search just for images or news...

Google can translate pages that are in a different language

Bad things about google:
