In the dark, ancient times of the Internet, it was difficult to find what you were looking for. Yes, there were search engines--Lycos, Webcrawler, Altavista, and others--but they were primitive tools, and able to index only the merest fraction of the web. Even if you mastered their arcane langauges, it was still sometimes impossible to find exactly the web page you were looking for.
Google changed all that. It indexes a massive swath of web on a frequent basis and it works well with natural language queries. That means you can type "how do I share an Aperture library with multiple computers" into Google, and it will usually take you to a reasonably helpful page.
But, Google has its own secret language. Most people know that you can put quotes around a query to let the search engine know to include precisely that phrase. You can even bypass the crappy search engines on many sites by specifying site:sitename.com in your query. But did you know about intext? If you preface a query with intext: that tells Google to only return pages that include that word or phrase in the article's body text.
John Tedesco collected a dozen or so great Google tips that I'd never seen before. They came from a talk Daniel Russell gave at the Investigative Reporters and Editors conference. Russell is a research scientist at Google. Everyone who uses the Internet should read this article.
