title: subscript for a join (\bowtie) operation in LyX/LaTeX
body: <p>I'm using LyX to write some Relational Algebra queries.
  I'm using the \bowtie symbol for the join operation but when I try to put a text in subscript directly under the symbol, I get the following error:</p>
  
  <blockquote>
    <p>...a_{\t{pId}}\t{person}\right)\bowtie\limits
                                                       <em>{\t{pId}</em>{1}=\t{pId}_{2}... I'm ignoring this misplaced \limits or
    \nolimits command.</p>
  </blockquote>
  
  <p>Anyone knows how to do what I want? Preferably in LyX, but ERT code snippets will also be appreciated. Thanks!</p>
  
  <p><strong>Edit:</strong> <code>\t</code> is a macro for <code>\text</code>.</p>
