distinguish between search queries

Introduce a new Id field for events to distinguish between
different searches.
Since search result reporting is split up a old search could introduce
results or terminate the current search.
Keep track of a search counter to distinguish between result from the
active search and stale ones.

Allow to add multiple songs from the current search.
