When your application needs recommendations for a specific person, get the
latest user history of interactions from the DB and query the indicator
collection with this history. You will get back an ordered list of item-ids.
These are your recommendations. You may wish to filter out any that the user
has already seen but that will depend on your use case.
+All ids for users and items are as preserved as string tokens and so work as
an external key in DBs or as doc ids for search engines, they also work as
tokens for search queries.
