Logging user searches and outcomes to obtain information on user preferences and actions

As a site manager I would like to be able to regularly (e.g. monthly) review search queries so that I can determine if I should be encouraging data providers to improve tagging of datasets for discovery or add additional datasets to the catalogue based on interest.

As a part of the log of user queries I would also like to know: what sorting order and filters were used, how many responses were provided to the search query (i.e. count), if the user selected a result from the search which one was it from the top of list (number) and what was the package id.

The issue names no files, tests, or entry points. Start by locating the search query, filtering, sorting, and result-selection flows, then determine how search events are currently recorded. Done means managers can review queries with the requested filters, sort order, result count, selected rank, and package ID.
