Vector Databases, Semantic search, and JSON

Cris and Matt talk about Vector databases, lexical vs. semantic search (and relevance ranking), and upcoming FileMaker conferences in Europe. Matt waxes poetic about JSON and a technique for storing certain types of data in a single, flexible JSON field, rather than having individual fields for everything. 
Cris recommends a book called 'AI for Good' by Juan M. Lavista Ferres,  William B. Weeks,  and Brad Smith. (Matt checked, and it's not yet available on Audible or Libby)
