Tags aid in searching. If a participant wants to find other waves that are tagged with “devlearn,” it may be more efficient to use that tag than to use Search.
There are quite a few waves that are very useful, run by users rather than by Google. Here are the ones that have become my favorites (you can find these by using Search from within Wave):

Make good use of the Search Cheat Sheet listed above. The search syntax in Wave is a bit arcane, or at least it seems so to me. Here are the terms I have been using most often, with a short explanation of each in parentheses:
with:public [keyword] (Finds public waves with that keyword in them, for example with:public Mobile Learning finds public waves that have Mobile Learning in the name or in the wave. Note that this also brings back waves that contain “Mobile, Alabama” – the Cheat Sheet explains the search operators that Wave uses, which are as arcane as the rest of the syntax.)
in:inbox (shows all the waves you are listening to)
by:me (all the waves I have contributed to)
by:[WAVid] (all the waves this person has contributed to)
When you first get your Wave account, any contacts in your Gmail address book who also have Wave accounts will automatically appear in your Contacts panel. (You must have a Gmail account to use Wave, by the way.) You can also add Wave users to your Contacts by searching for them, or by opening the “Manage Contacts” link and typing their WavID.
if you open the Inbox link in the Navigation panel, any and all waves in it will appear in the Search panel. The same is true if you open, for example, one of your folders.
The ellipsis at the end of the ribbon opens up a drop-down menu of other functions, such as moving a wave to a different Folder.
