In this paper I combine an overview of the goals and major approaches in cross-language information retrieval with some observations of current trends and with a report on a CLIR project that differs in many respects from most research activities in the fast growing area. In the overview, I will start from a generic model of an information retrieval system. Then the necessary extensions will be introduced that are needed for allowing queries in a language different from the document language. Several options for adding translation technology will be contrasted. I will then report on the research strategy followed in the EU-funded international project Mulinex. In this project a complete modular CLIR system was developed and integrated as the core software for a number of applications and as a plattform for research and technology development.
