Yahoo used to have an independent search engine but switched to using Microsoft Bing (for the most part) in 2010.

Previously: one of several independent search engines that index and support microformats.

search site

search APIs and tools

BOSS

Yahoo supported a custom search API called BOSS until 2016-03-31 which had built-in microformats support.

SearchMonkey

Yahoo SearchMonkey supported hCard 1.0, hCalendar 1.0, hReview 0.4 (in progress), hAtom 0.1, others - launched 2008 May, updated 2008-12-07, until it was shut down in 2010 October. SearchMonkey was Yahoo!'s program for collecting and displaying structured data, including microformats.

YQL

Yahoo Query Language used a SQL-like syntax to "normalize" web service calls. In addition to wrapping web services such as Flickr, Yelp, and Zillow, YQL also enabled you to extract content directly from web pages. As part of that functionality, YQL could query and filter on microformats from 2009-01-13 until YQL shut down on 2019-01-03.

For example, the YQL query:

http://query.yahooapis.com/v1/public/yql?q=select * from microformats where url%3D'http%3A%2F%2Fupcoming.yahoo.com%2Fvenue%2F23933%2F'&format=xml

extracts all microformats from a particular page on upcoming.yahoo.com.

Unlike BOSS and the simple microformat filters described above, you can use YQL to perform filtering and other operations on the microformat data itself.
