Autocomplete offers search suggestions when a user starts entering characters in the
search bar as in the picture below.
Autocomplete also speeds up the search for users, saves time, and ensures that no search ends with
"no results" page.
Filtering and sorting options allow customers to narrow down the search results and make it easier to find the desired product. The most commonly used
filters are size, color, and material, depending on the products' options. Sorting usually includes price, popularity, and availability.
Synonyms help users to find similar products they may also like. For example, a person searching for a "pullover" may also be interested in a "fleece jacket". To extend search results this way,
synonyms are required.
Analytics provides data on your users' search inputs. It allows you to gain a better understanding of customer's behavior and use these insights for further business development. For example, you can take a look at zero-result search queries and add the most often searched products to your store.
