<entry-title>Yahoo Search</entry-title>
Yahoo is one of several search-engines that index and support microformats.
main search
search.yahoo.com supports rel-nofollow (since 2005(?) citation needed).
advanced search
Through additional user interfaces:
- Yahoo Creative Commons search supports rel-license
search APIs and tools
Yahoo provides search APIs like:
BOSS
- Yahoo Search BOSS
- When calling the BOSS web search API, you can retrieve all structured data Yahoo! has extracted for the specified URLs via SearchMonkey, including any microformats. Just add the parameters "view=searchmonkey_feed&format=xml" to your web search API call. This is probably the most efficient way to fetch structured data from Yahoo!.
- Build a semantic Search Engine with BOSS documents how to use Yahoo's BOSS API to access Yahoo SearchMonkey which supports the hAtom, hCalendar, hCard, hReview, XFN, geo, rel-tag, adr microformats.
SearchMonkey
Yahoo SearchMonkey supports hCard, hCalendar, hReview, hAtom, others - launched 2008 May. SearchMonkey is Yahoo!'s program for collecting and displaying structured data, including microformats.
- You can inspect microformat and other structured data gathered by SearchMonkey by going to the SearchMonkey Developer Tool. However, if you are only interested in microformat data (i.e. you are not planning on building a full-fledged SearchMonkey application), it is more efficient to use BOSS or YQL.
- To inspect structured data directly on the Yahoo! Search page, install the Structured Data Display infobar.
- Microformat filtering on Yahoo! Search: The general form is "searchmonkey:com.yahoo.page.uf.<microformat> <additional query terms>". For example, you could search for all pages with hResume and the word "php". Note that "searchmonkey:" acts as a filter. You aren't inspecting the actual hResume content for the word "php", you are searching for all pages that A) have hResume and B) would be returned by an ordinary Yahoo! Search for "php".
- search Yahoo for hCards
- search Yahoo for hCalendar events
- search Yahoo for hReviews
- search Yahoo for hAtom
- search Yahoo for XFN
- search Yahoo for hResume
- search Yahoo for adr
- search Yahoo for GEO
- search Yahoo for rel-tag
- All of these microformat filters can be used with the BOSS API as well.
YQL
Yahoo Query Language uses an SQL-like syntax to "normalize" web service calls. In addition to wrapping web services such as Flickr, Yelp, and Zillow, YQL also enables you to extract content directly from web pages. As part of that functionality, YQL can query and filter on microformats. For example, the YQL query:
extracts all microformats from a particular page on upcoming.yahoo.com.
