Process of Setting Up Attribute Search
Users can choose to search for products using values of the attributes of those products. This search is known as attribute search, and it is sometimes also known as parametric search.
Attribute search allows users to take advantage of the class system. Instead of entering free-form search strings into a full-text search engine, users of attribute search can select from known attributes (for example, color, size, shape, and maximum temperature) of a particular class of products.
