Yahoo Search is a web search engine owned by Yahoo! Inc., and was, as of January 2014[update], the second largest search directory on the web by query volume, at 5.45%, after its competitor Google at 71.36%, according to Net Applications.
Originally, "Yahoo Search" referred to a Yahoo-provided interface that sent queries to a searchable index of pages supplemented with its directory of sites. The results were presented to the user under the Yahoo brand. Originally, none of the actual web crawling and storage/retrieval of data was done by Yahoo itself. In 2001, the searchable index was powered by Inktomi and later was powered by Google until 2004, when Yahoo Search became independent.
Search technology acquisition
Seeking to provide its own search engine results, Yahoo acquired their own search technology.
In 2002, they bought Inktomi, a "behind the scenes" or OEM search engine provider, whose results are shown on other companies' websites and powered Yahoo in its earlier days. In 2003, they purchased Overture Services, Inc., which owned the AlltheWeb and AltaVista search engines. Initially, even though Yahoo owned multiple search engines, they didn't use them on the main yahoo.com website, but kept using Google's search engine for its results.
Starting in 2003, Yahoo Search became its own web crawler-based search engine, with a reinvented crawler called Yahoo Slurp. Yahoo Search combined the capabilities of all the search engine companies they had acquired, with its existing research, and put them into a single search engine. The new search engine results were included in all of Yahoo's sites that had a web search function. Yahoo also started to sell the search engine results to other companies, to show on their own web sites. Their relationship with Google was terminated at that time, with the former partners becoming each other's main competitors.
In October 2007, Yahoo Search was updated with a more modern appearance in line with the redesigned Yahoo home page. In addition, Search Assist was added; which provides real-time query suggestions and related concepts as they are typed.
In July 2008, Yahoo Search announced the introduction of a new service called "Build Your Own Search Service," or BOSS. This service opens the doors for developers to use Yahoo's system for indexing information and images and create their own custom search engine.
Yahoo Search blog and announcements
The team at Yahoo Search frequently blogged about search announcements, features, updates and enhancements. The Yahoo Search Blog, as stated provided A look inside the world of search from the people at Yahoo. This included index updates named Weather Updates and their Yahoo Search Assist feature.
Yahoo Search also provided their search interface in at least 38 international markets and a variety of available languages. Yahoo has a presence in Europe, Asia and across the Emerging Markets.
Yahoo Search indexed and cached the common HTML page formats, as well as several of the more popular file-types, such as PDF, Excel spreadsheets, PowerPoint, Word documents, RSS/XML and plain text files. For some of these supported file-types, Yahoo Search provided cached links on their search results allowing for viewing of these file-types in standard HTML.
Using the Advanced Search interface or Preferences settings, Yahoo Search allowed the customization of search results and enabling of certain settings such as: SafeSearch, Language Selection, Number of results, Domain restrictions, etc.
For a Basic and starter guide to Yahoo Search, they also provided a Search Basics tutorial.
In the first week of May 2008, Yahoo launched a new search mash up called Yahoo Glue, which is in beta testing.
On June 20, 2007, Yahoo introduced a selection-based search feature called Yahoo Shortcuts. When activated this selection-based search feature enabled users to invoke search using only their mouse and receive search suggestions in floating windows while remaining on Yahoo properties such as Yahoo Mail. This feature was only active on Yahoo web pages or pages within the Yahoo Publisher Network. Yahoo Shortcuts required the content-owner to modify the underlying HTML of his or her webpage to call out the specific keywords to be enhanced. The technology for context-aware selection-based search on Yahoo pages was first developed by Reiner Kraft.
Yahoo Search provided the ability to search across numerous vertical properties outside just the Web at large. These included Images, Videos, Local, Shopping, Yahoo Answers, Audio, Directory, Jobs, News, Mobile, Travel and various other services as listed on their About Yahoo Search page.
