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.
