The JSON doc has this example (to show the need for double backslash):
$ ? (@ like_regex "^\\d+$")
The example is not wrong exactly, and can be cast to jsonpath, but as-is
can never match anything.
I think it'd be helpful to provide that example so that it more probably
matches when the user does a quick trial.
Llet's change it to something like:
$.* ? (@ like_regex "^\\d+$")
Patch attached.
thanks,
Erik Rijkers

backslashes you want to use in the regular expression must be doubled.
For example, to match strings that contain only digits:
<programlisting>
-$ ? (@ like_regex "^\\d+$")
+$.* ? (@ like_regex "^\\d+$")
</programlisting>
</para>
