Search function for topics

Firstly i want to say i love Glow and am so glad that as an Android user, that I can finally see groups and more.

One thing that I think would make things easier from a user point of view is having a search function to look for topics that interest me.

An example: if someone wanted to find out mor about preseed. They would enter preseed into tje search field and presto all topics pertaining to preseed would be listed.

I don't know if this feature is available for iPhone users but i couldn't find it on android. Would love to hear others thoughts? ☺
