  +<p><b>Expression shortcut:</b></p>
  +<ul>
  +<li>Since it is very common need to perform a case-insensitive partial-text match
against the Message field, any single word or any single phrase (the phrase must be delimited
by single-quote marks) will act as a rule defined using the MSG ~= syntax.</li>
  +<li>Example: to search the Message field for the phrase 'logged in', instead of defining
the expression <b>MSG ~= 'logged in'</b>, use <b>'logged in'</b> by
itself (including the single quotes).  Instead of using <b>MSG ~= evaluation</b>
to search for the word 'evaluation', use <b>evaluation</b> by itself (no need
for single quotes since it's a single word).</li>
  +</ul>
  +
   <p><b>Operator limitations:</b></p>
   <ul>
   <li>Inequality operators are supported for Levels (<b>LEVEL &gt info</b>)
and anything that can be converted to a numeric value (including timestamps).</li>
