+<item id="dot_asterisk" h="Regular Expressions starting or ending with “.*”">
+It is not necessary to put <tt>.*</tt> or <tt>.*?</tt> into the beginning or
+expressions to match something anywhere inside the string. So for example
+<tt>if ($hay_stack =~ /.*ab+c.*/)</tt> can be replaced with the simpler:
+<tt>if ($hay_stack =~ /ab+c/)</tt>. If you wish to match and extract the
+prefix, you should say <tt>(.*?)</tt> or <tt>(.*)</tt>.
