Generalizing GlOSS to Vector-Space Databases and Broker Hierarchies

Summary: gGlOSS extends GlOSS from Boolean to vector-space retrieval, using database statistics to rank useful text sources for a query. Hierarchical brokers yield a tiny, widely replicable top-level directory; evaluated with real queries over 53 databases. (summarized by gpt-5.6-luna on Jul 24 2026)
