TiTLi is a Google-like search tool for relational databases . It builds on top of Apache Lucene to provide an API and a GWT-based UI for searching multiple databases from various vendors simultaneously. It is very fast due to indexing, and the database is queried only when a record is chosen.
Isobel is a framework to build complex information retrieval and analysis systems. Isobel can be functionally divided in two subsytems, Isobel Gatherer (the crawling and filtering subsystem) and Isobel Analyzer (the analysis subsystem). The two subsytems can also be used separately. Isobel Gatherer offers ready-to-use services like content fetching, scheduling, document format conversion, Hyperlink graph storage and analysis, content storage and indexing. A programmer may easily add new services. Isobel Analyzer uses the IBM UIMA architecture to reuse the analysis components developed for this architecture.
