Filters and sub-search on results

[j-jaworski]

As a user I need to filter and narrow results So that I can get a smaller, more relevant set of data

This issue will need further ideation and exploration:

• what filters are possible
• what filters are useful to users
• Date range, sub-search, checkbox orgs etc

The designs for how we might implement filters can be found across the latest work on zeplin

Multiselect dropdown filters with states https://zpl.io/aX8x7Dl

Subs -search and applied filters https://zpl.io/a7NA7xY

Custom date range selector https://zpl.io/bWJo7Jj
