eBay’s Fast Billion-Scale Vector Similarity Engine

One of the best things about eBay compared to other market places like Amazon and Aliexpress, is that their search operators include not just AND (space) but also OR (comma separated values inside parentheses) and NOT (minus) but more importantly - eBay's search engine respects the supported operators and denoting which items are search results and which are suggested/similar.

This cannot be said about Amazon, Aliexpress, both which intentionally (I guess) mix similar items with results that match the search query.

I hope that eBay keep those two things distinct.

And you can setup email alerts for those complex search terms.

I made a tiny amount of money doing typo arbitrage on bundles labelled as “Nitendo” many years ago.

Sometimes when I wanted a really niche item, I’d wait for one of those alert emails that had more than usual results because I knew the bidding would be split.

I dislike eBay search, for example all of a sudden one of my daily bookmarked searches went from the usual 10 results to THOUSANDS, all of them not including my search term, this is the link: https://www.ebay.co.uk/sch/i.html?_nkw=Tasmota&LH_PrefLoc=1&...

Why are some sellers having all their listings (car parts) included in my search for "Tasmota"?

That's interesting, I've seen it happening randomly that a search query would return unrelated results for 1 out of 100 queries using the same query.

In your example however, it seems to me that if you add quotes, the irrelevant results are gone: https://www.ebay.co.uk/sch/i.html?_nkw=%22Tasmota%22
