Delete unavailable items in search page

[yujinkimmn]

Is your feature request related to a problem? Please describe.

When I click the upper left menu icon, and enter the 'Search page', I can see the result of 'Recent searches'. However, even when each item is unknown and unavailable, it still appears on the list. I think it could be more convenient to delete them, instead of showing them as 'Not available'.

Describe the solution you'd like

Delete the 'Not available' items on Recent searches list.

Describe alternatives you've considered

Just get rid of them from the list and provide convenience to user in terms of UI.
