GraphQL Client adoption: Search

[umpox]

We’re looking to increase adoption of Apollo Client across search components.

The aim of this issue is to identify and eventually improve areas of search that:

• Would benefit from serving cached data. High-traffic areas where data is unlikely to change whilst the user is on the page.
• Would benefit from refactoring data fetching logic into a shared API. Some examples may be complicated RxJS code that could be abstracted, or usage of FilteredConnection that has proven difficult to modify previously.

Please use this issue to discuss and identify these areas. Will create follow-on tickets to track implementation.
