<para>

The <literal>.**</literal> accessor can lead to surprising results

when using the lax mode. For instance, the following query selects every

<literal>HR</literal> value twice:

<programlisting>

lax $.**.HR

</programlisting>

This happens because the <literal>.**</literal> accessor selects both

the <literal>segments</literal> array and each of its elements, while

the <literal>.HR</literal> accessor automatically unwraps arrays when

using the lax mode. To avoid surprising results, we recommend using

the <literal>.**</literal> accessor only in the strict mode. The

following query selects each <literal>HR</literal> value just once:

<programlisting>

strict $.**.HR

</programlisting>
