                  a page at a time and can be filtered at the broker using the <code>filter</code>: see <a href="https://activemq.apache.org/components/artemis/documentation/latest/filter-expressions.html" target="_blank">Filter Expressions</a>
                  . To execute a query click on the <span class="fa fa-search"></span> button.

                <p>
                    Clicking on the <code>show</code> buton will show the messages details in more detail including, headers, properties
                    and the body if viewable. Clicking on the <code>resend</code> button will navigate to the <code>Send Message</code>
                    tab and copy the message details so a copy of the message can be resent. You can also use the cassette
                    buttons to move to the next/previous message, next/previous page or first/last page.
