AliExpress has one of the largest product catalogs on the planet, but its search assumes you already know the exact English keyword. I spent a while building OneFindMe , a free multilingual search layer that sits in front of AliExpress, and these were the lessons that actually moved the needle. The fix was to resolve the shopping intentto a canonical product query first, then translate that — not translate the raw phrase. A small curated keyword map beat the general model for the high-traffic terms, because the model kept inventing plausible-but-wrong category ids. Only the first few words of a query survive Long, descriptive queries rank worse than short ones on the marketplace API.
