Start with the product and a few essential features. Add a delivery country and a price range. Keep the request short and specific.
Which information helps?
For example: Find a wired mechanical keyboard, 75 percent layout, ISO-DE, under 60 euros, delivered to Germany. Product type, layout and connection are separate requirements. You can search in different languages.
What should a follow-up change?
Change one condition at a time: Show wired models only or Raise the price limit to 80 euros. This helps you see which condition narrows the selection. Ask which requirements the returned offers actually meet.
When should I name an exact model?
A model code or connection standard can narrow the search. Still explain the features you need. A title alone does not prove waterproofing, for example. If too few results appear, try a more general product description.
