No longer able to search within my list of eBay items. Workaround?

Until this week, we used to be able to click on ‘See other items’ from within one of our listings and it opened a page where we had a search box which only searched our items.
I found this very useful when I have more than a page of listings.
It’s gone now so I’m wondering if there is a workaround or even better, a setting that brings it back? Thanks
