Can an Activity Stream use a search field?

[DeltaOne]

I think it would be useful if one could use a search item as one of the variables when setting up an Activity Stream.

 

For example, the "Live from..." message threads are very popular.  It would be a great feature if one could set up an Activity Stream for finding the "Live from..." message threads.

 

This wouldn't work for those that don't use the word "Live" in their thread title...but most do use "Live" and maybe we could encourage everyone to do so.
