Parametric search is a type of search that adheres to predefined attributes present within a given data source.
Parametric search makes it easier for users to find the results they are looking for by using multiple criteria or parameters. This type of search is often combined with filters to narrow down results based on specific criteria.
For example, suppose a user wants to find a product on an e‑commerce site. In that case, they can use parametric search instead of keyword searching, which would involve manually keying in every relevant word or phrase.
With parametric search, the user can fill in specific details instead, such as brand name, color, size, etc., and the search engine will produce results tailored to their needs.
