Google’s advanced search options are useful, but they could include ways to define more restrictions for search results. Maybe you want to find pages that mostly contain text, web pages that reference videos or include tables. Fortunately, some these features are available at Yahoo, where you can use the feature: operator.

To find web pages that link to files with a certain extension, use the linkextension: operator. For example, linkextension:ogg bach finds web pages about Bach that link to .ogg audio files.

Yahoo has another interesting operator (depth:) that lets you define the maximum number of subdirectories from your search results’ URLs. For example, a search for google tips depth:1 will include www.google.com/help/features.html because it has a single directory, but not www.techcrunch.com/2007/01/04/google-tips-pulled, which has three directories. This could be useful to find web pages that are important relatively to the structure of a web site.

The operator has a special value that lets you search only homepages: -1, as you can see in this query: flickr depth:-1.

I don’t know if Yahoo’s search engine is better than Google, but Yahoo inherited a lot of interesting features from AltaVista and Inktomi, two leading search engines in the ’90s.

To get a more targeted search, try these tricks out:

• Words within square brackets — adding square brackets to your search makes the keyword match order dependent. So typing in ‘[Jack Black]‘ will return results such as ‘jack with black’ but not ‘black jack.’
• “inurl” — if you want to be sure that a specific term will appear in the site’s URL, use the “inurl:[query]” operator. For example: ‘inurl:iPod.’
• Site restriction — to restrict your search to pages within a specific domain, use the “site:[domain]” operator, followed by your query. For instance: ‘Site:Apple.com iPod.’
• “orginurlextension” — to search on specific file types, add ‘originurlextension:[file format]’ after your search query. For example: ‘nanotechnology originurlextension:swf‘ OR ‘nanotechnology originurlextension:pdf.’

Package Tracking
Did you know that you can track your packages right in Yahoo! Search? Here’s How it works:

• For UPS packages, simply type in your tracking number
• For FedEx or the U.S. Postal Service, just add the name before the tracking number. For example: ‘FedEx [tracking number]’ or ‘USPS [tracking number]’

Yahoo! Open Shortcuts
Yahoo! Open Shortcuts are the ultimate time-saving search feature. Add an exclamation point to the front of certain terms to instantly navigate to a URL, search a site, recall a favorite Yahoo! search, or start an application.

• ‘!wiki queen elizabeth‘ takes you directly to the Wikipedia page for Queen Elizabeth.
• ‘!wsf‘ gives you the Yahoo! Search results for “weather San Francisco.”
• ‘!clist‘ takes you to Craigslist.
• ‘!ebay lamps‘ searches eBay for lamps.

Search for ‘!list‘ to see a bunch more. Those examples have already been set up for everyone to use, but the real power is that YOU can create your own customized shortcuts.
