We describe how we constructed a Java class library for text mining and information retrieval. The system consists of Facades around a database, a search engine and a text mining tool. We discuss the design of the object models we used for each of these elements and how they evolved as different databases and search engines became available. Then we discuss how we needed to evolve the system further in work with our customer. Finally we discuss the eventual fate of the system after the customer adopted the final version of the code, showing what we learned from the experience.
