I want to start pointing people to Quarry when they ask for specific data that can be obtained via the public replicas of our production DBs. Having either tags or simple search functionality will allow us to put together a query library.
Queries can be searched by title or summary (will hopefully motivate people to provide summaries). Search box appears in "Recent queries" page. Allow users to search either ALL queries, or just published queries. Users can use Hashtags in query summaries to search by tag.
