From Windows File Explorer you can use the search and then drag the media into your project, but its a little difficult to audition the sample and on the other hand you can audition the samples from the media browser inside of sonar but can't find the media you want - is that like a loss-loss situation, as apposed to a win-win?
Use the Media Browser view that works like Explorer. From the Media drop-down menu, choose View > Folders.
The left pane of the media browser turns into something that looks like Explorer. Now, suppose you enter "kick" in the search box. When you double-click a folder in the "Explorer" pane, if there are kicks, they will be listed in the right-hand pane. By double-clicking through your folders, you'll be able to see if that folder contains kicks, and those kicks will appear in the right pane as long as "kick" remains in the search box.
This isn't as good as having a search function that returns every kick in every folder, but it makes life a lot easier.
Another cool thing about Folders view is that if you choose a particular type of content (like PTN files) in the content box, the folder view will show where those files are located. Yes, I finally know where the RXP content is located...
These kinds of tips are in the article I did for the March issue of Sound on Sound.
