title: MongoDB "error command line: unknown option setParameter" when turning on textSearchEnabled
body: <p>I'm trying to experiment with mongoDB's new full text search:</p>
  
  <p><a href="http://docs.mongodb.org/manual/tutorial/enable-text-search/" rel="nofollow">http://docs.mongodb.org/manual/tutorial/enable-text-search/</a></p>
  
  <p>However, when I either use the parameter in the mongod command, or in a config file, I get the following error:</p>
  
  <pre><code>[root@bobby etc]# /usr/bin/mongod --dbpath /home/bobby/data/ --setParameter textSearchEnabled=true 
  error command line: unknown option setParameter use --help for help 
  </code></pre>
  
  <p>And I'm running the latest version of MongoDB on Scientific Linux</p>
  
  <pre><code>[root@bobby etc]# mongo 
  MongoDB shell version: 2.4.3 
  connecting to: test
  </code></pre>
  
  <p>Interestingly, setParameter isn't listed in --help either:</p>
  
  <pre><code>[root@bobby etc]# /usr/bin/mongod --help | grep setParameter
  (nothing)
  </code></pre>
