title: SPSearch in CocoaLibSpotify
body: <p>I'm looking at CocoaLibSpotify, and trying to get a simple search request working.
  I make the request like this:</p>
  
  <pre><code>SPSearch *search = [[SPSearch alloc] initWithSearchQuery:@"Adele" inSession:[SPSession sharedSession] ];
  </code></pre>
  
  <p>And am then polling for the search to return with:</p>
  
  <pre><code>[search searchInProgress]
  </code></pre>
  
  <p>But I never see searchInProgress return a NO - ie. the search does not appear to ever complete.</p>
  
  <p>I've searched through the documentation and examples but it hasn't helped me to understand how to use the SPSearch correctly - would definitely welcome some help here...</p>
  
  <p>Thanks,
  Iain </p>
