  <synopsis>
  <replaceable>a</replaceable> &lt; <replaceable>x</replaceable> OR 
<replaceable>a</replaceable> &gt; <replaceable>y</replaceable>
  </synopsis>
+     There is special variant of this operator <indexterm><primary>BETWEEN 
SYMMETRIC</primary></indexterm>.
+     In this case isn't important <replaceable>x</replaceable> &lt;= 
<replaceable>y</replaceable> and
+     <replaceable>a</replaceable> BETWEEN SYMMETRIC 
<replaceable>x</replaceable> AND <replaceable>y</replaceable>
+     is equivalent to
+ <synopsis>
+ (<replaceable>a</replaceable> &gt;= <replaceable>x</replaceable> AND 
<replaceable>a</replaceable> &lt;= <replaceable>y</replaceable>) OR 
(<replaceable>a</replaceable> &gt;= <replaceable>y</replaceable> AND 
<replaceable>a</replaceable> &lt;= <replaceable>x</replaceable>)
+ </synopsis>
+     Similarly,
+ <synopsis>
+ <replaceable>a</replaceable> NOT BETWEEN SYMMETRIC 
<replaceable>x</replaceable> AND <replaceable>y</replaceable>
+ </synopsis>
+     is equivalent to
+ <synopsis>
+ (<replaceable>a</replaceable> &lt; <replaceable>x</replaceable> OR 
<replaceable>a</replaceable> &gt; <replaceable>y</replaceable>) OR 
(<replaceable>a</replaceable> &lt; <replaceable>y</replaceable> OR 
<replaceable>a</replaceable> &gt; <replaceable>x</replaceable>)
+ </synopsis>
+     
      There is no difference between the two respective forms apart from
      the <acronym>CPU</acronym> cycles required to rewrite the first one
      into the second one internally.
