Yahoo! Teams with Open Text to Offer Most Comprehensive & Efficient Searches on the Net

Open Text's Web Search Server Technology Expands Yahoo!'s Online Guide with Internet-Wide Search Capabilities and Word-by-Word Indexing

New York, N.Y. -- September 18, 1995 -- Yahoo! Corporation, publisher of the most intuitive, up-to-date and efficient guide to the online world, and Open Text Corporation, developer of the Internet's most powerful text indexing and search engine, announced today a partnership to incorporate the Open Text Web Search Server OEM technology into the Yahoo! online guide. This partnership will enhance Yahoo! with the powerful Internet-wide, word-by-word search capabilities of the Open Text 5 search engine and enable the guide to satisfy all of the diverse search needs of Internet users. Users will get their first glimpse of Yahoo!'s expanded search capabilities in early October.

"We're partnering with Open Text because our technical evaluation showed Open Text to be the most powerful indexing technology available to enhance our online guide," said Jerry Yang, co-founder of Yahoo!. "The Open Text technology expands Yahoo! with an intelligent `back of the book' word-by-word index of the entire Internet, which complements Yahoo!'s `front of the book' comprehensive hierarchical index. This integration boosts the efficiency and productivity of both browsing and more serious searching on Yahoo!, and therefore broadens Yahoo!'s appeal to a wider range of Internet users."

Tom Jenkins, president and CEO of Open Text commented, "As the premiere guide to the online world, Yahoo! is doing exactly what our Web Search Server technology was designed to accomplish - satisfy the needs of consumers and working professionals by enabling them to more easily navigate through the Internet and gather meaningful information. We've established a close working relationship to drive the tight integration of Yahoo! with our Web Search Server OEM took kit. Together, we're giving Internet users an unbeatable combination of directory-based and intelligent full-text searching unavailable anywhere else on the Net."

Under the terms of the partnership, Yahoo! will seamlessly integrate the Open Text Search Server technology into its guide's intuitive hierarchical index format. The Open Text technology uses automated software called "crawlers" to index every word and every page of the entire Internet. These crawlers re-visit Web pages on an ongoing basis to ensure the Open Text master index remains current. The integration of Open Text's technology into Yahoo! will position Yahoo! as the most comprehensive guide to the online world with the most efficient category-based, Internet-wide search capabilities.

Yahoo!'s Enhanced Search Capabilities

Yahoo!'s implementation of the Open Text Web Search Server technology will enable its users to conduct simple searches for specific words and phrases, multi-level Boolean searches and even weighted searches. These searches can be narrowed to specific categories in Yahoo!'s hierarchical index. Yahoo! users also will benefit from the Open Text 5 search engine's ability to understand the structure and elements of Hypertext Markup Language (HTML), the language used to create Web documents. This unique feature enables Yahoo! users to use structural considerations such as document titles, sub headings, body copy and footnotes as qualifiers for their searches. Additionally, the Open Text technology will uncover documents "similar" to those a user has already found. This capability allows Yahoo! users to expand their searches gradually, based on highly flexible criteria.
