Algolia is helping e-commerce sites improve their search interfaces with query suggestions, which are currently used by only 19% of sites. To implement it correctly, users need to collect and send data to Algolia's servers, create a new index for Query Suggestions, and configure settings such as ban tools and result limits. Once set up, the index will start building itself, allowing developers to focus on displaying the data to the frontend. The plugin can be loaded into the autocomplete instantiation, tying it to the new index, and users can also add scoped or category-specific suggestions, filters, and other features to reduce friction in the search experience.
