I have found what appears to be a bug.  Putting "algorithm" as a tag to search for it returns:<p><pre><code>    1 Computer algorithm to decipher ancient texts (reuters.com)
      (1 point) (discuss)(tag)tags: hacking algorithm
	
    2 Computer algorithm to decipher ancient texts (reuters.com)
      (2 points) (discuss)(tag)tags: hacking algorithm
</code></pre>
The discuss links, however, go somewhere weird and apparently unrelated.
