Abstract

Majority of Austrian research relevant information available an the Web these days can be indexed by web full-text search engines. But there are still several sources of valuable information, which cannot be indexed directly. One of effective ways of getting this information to end-users is using metasearch technique. For better understanding it is important to say that metasearch engine does not use its own index. It collects search results provided by other search engines, and builds a common hit list for end users. Our prototype provides access to five sources of research relevant information available an the Austrian web.
