When I implemented search for my app, I built a hierarchy of the different attributes weighted by levels and scored search phrases for how closely they matched.

When I implemented search for my app, I built a hierarchy of the different attributes weighted by levels and scored search phrases for how closely they matched. This is for mobile phones. For example, searching for "Silver iphone 11 pro" would give a higher ranking to all iphone 11 pros that are Silver, then comes differently coloured 11 Pros, followed by 11 Pro Max and 11s, lastly all silver coloured phones.
