Not sure why the extra parameters (submit and id) after the s=tierney part are necessary, but the problem is the ellipse in the value for submit: &submit=Search…. If you remove the ellipse, then this URL returns the right search results:

https://dailybusinessgroup.co.uk/?s=tierney&submit=Search&id=75070

When I look at the code for the Search form, I see this:

<form method="get" id="searchform" class="nptitems" action="https://dailybusinessgroup.co.uk/">
	<label for="s" class="assistive-text"></label>
	<input type="text" class="field" name="s" id="s" placeholder="Search..." />
	<input type="submit" class="submit" name="submit" id="searchsubmit" value="Search..." />
	<input type="hidden" name="id" value="75070" />
</form>

So what needs to be done is the value for the submit button (which is the second input tag listed above) needs to have the ellipse removed from the value property.
