Investigate how to archive search access activity

[bgajdero]

We want to know what users are searching for and their behaviour. This is a precursor to Issue https://github.com/csse-uoft/ckanext-udc/issues/14

What's the best way to do it?

• Is saving access logs the best way?
• Should we create a module in the plugin to collect data directly from sessions, access logs, etc?

For example, if it's taken from access logs, we need to archive the logs for future analysis. Access logs are deleted after some period of time. We want to save log entries that identify search queries. Select search log entries and archive them in a persistent file.

Will be relying on filter instead of access logs, replaced with https://github.com/csse-uoft/ckanext-udc/issues/30
