Search is really broken in numerous ways right now.
There is something wrong with that first URL.
https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2334524.m570.l1313.TR0.TRC1.A0.H0.Xperdiz+.TRS2&_...&_trksid=p2334524.m570.l1313.TR0.TRC1.A0.H0.Xperdiz+.TRS2 doesn't look right (I have no idea how those trksid values are generated of what they mean, but that one looks mangled and just wrong)
_nkw=perdiz+ is also wrong - there shouldn't be a + sign on the end, or there is supposed to be texas on the end.
Where did that first URL come from?
