V1 (deprecated)

4 min

The v1 APIs are now deprecated! If you are building a new implementation, we strongly recommend using API version 2 by going through V2 Overview

Depending on what details you want Klevu Search servers to return in response, you can use one of the following API methods to search in your index.

For the “search as you type” sort of interface where you need query suggestions, matching categories, CMS pages and product suggestions, please use the “Search As You Type” method.
For the search results landing page, if you only need a list of IDs of records relevant to your query, use the ID Search method.
In addition to record IDs, if you want Klevu Search to return other details such as name, description, price, etc., use the Record Search method.

Both the ID Search and the Record Search methods have parameters that allow you to fetch filters/facets as well.

Search As You Type
