eBay fudging search results?

[Ichinisan]

I've sold a few things on eBay recently. By searching sold/completed listings, I can only find the NES that I sold. I can't find either of the 2 N64 systems, no matter which combination of search terms I use.

Jungle Green N64 w/ UltraHDMI Ultra HDMI IGR in game reset Nintendo 64 Funtastic
+ Controller, Expansion Pak, Bag, HDMI, BEST NINTENDO64
Sold by best offer​

N64 + UltraHDMI + IGR + controller SHIPS FREE ultra hdmi nintendo 64
Very good atomic purple controller, great thumb stick!
Sold by best offer​

I should be able to search completed listings for "UltraHDMI" and find these, but it doesn't work. I tried "Ultra HDMI N64" also, and that doesn't work either. I want to sell more, but I want my future buyers to have confidence in seeing that I have sold these before.

So here's something I sold in a similar time frame, and I have no problem finding it:

Nintendo NES-101 + Hi-Def NES HDMI mod INSTALLED, dogbone controller top loader
With warranty! Very good condition. Good capacitors.
Sold for fixed price​

I just search sold or completed listings for "NES HDMI" and it comes right up. The only difference I see is that the 2 listings I can't bring up were sold by Best Offer. Did eBay recently start suppressing Best Offer sales from search results for sold / completed listings?

I'm pretty sure I saw search listings within the last week where it showed that best offer had been accepted.

I called eBay and they just said to check back in a couple days.

In my typical experience, an auction item immediately comes up in sold/completed results as soon as it ends. Maybe fixed-price listings or best-offer sales take some time to show up for some reason.
