title: redis and tags for a large video site
body: <p>My question is regarding tags and searching, for a tube/flash based
  video clip site.</p>
  
  <p>I have apx 100,000 videos which I want to organize using Redis.</p>
  
  <p>Each video has the following:</p>
  
  <p>Title, length, tags</p>
  
  <p>I've been adding the clips with the following</p>
  
  <pre><code>hset video:id1 title  "A funny clip"
  hset video:id1 length "22 secs"
  hset video:id1 tags   "funny,accident,cat"
  
  hset video:id2 title  "Falling of a chair"
  hset video:id2 length "33 secs"
  hset video:id2 tags   "funny,chair,kids"
  
  hset video:id3 title  "Pool party"
  hset video:id3 length "17 secs"
  hset video:id3 tags   "funny,pool,accident"
  </code></pre>
  
  <p>What do I do now to allow for searching by tags.</p>
  
  <p>I'd like to be able to do a search for all the clips which have 
  certain tags.</p>
