Abstract e-Business architecture has been updated dramatically for the
past 10 years. The architecture moved from the traditional client-server architecture to n-tier architecture since Internet and Web came out to the world. Internet and web even create new product and revenue as companies have invested in Information Technology seriously not as an option. Content is one of the examples in this new era. Content has become intellectual property and a company or organization that has content can make profit by providing the content to the customers and the users. As the content increases high, there is a need for search engine in order to provide the proper content to the user quickly. Thus, search engine has received highlight in the content industry, mostly portal sites. The paper introduces search engine - especially internal search engine not web search engine - and its fundamentals. Then, e-Business architecture with search engine is illustrated.
