I'm not sure if you mean indexing implementation, or indexing of my model objects. Indexing functions take model data and return: * single index value which can be an UUID or a string * single index value with multiple elements (e.g. a vector) * multiple index values They are Clojure functions, operating on Clojure data, testable with Clojure tests. As opposed to many other solutions, they do not live in the database, are not written in a limited database language with limited data types, and they operate on native (not coerced to db form) data values. Since they are functions of your data, you are not limited to indexing on a field or a combination of fields, you can compute a value (or values) based on your data. The indexing implementation runs these when needed to get index values from model objects, and updates the actual index "tables" (areas in the key-value space, really).
