The AddSearch Frequently Bought Together (FBT) tool identifies and recommends sets of products or documents which are frequently purchased or viewed together. For example, users can be recommended related news articles or items which are often combined in purchases.

The FBT feature uses the Fp-growth algorithm. This is a frequent-pattern mining algorithm used for finding frequent items in a dataset. It uses a tree-based data structure called the frequent pattern tree (FP-tree) to efficiently discover frequent itemsets.

To use the FBT tool, a dataset will need to be added via the AddSearch dashboard or pushed using the Indexing API. Once this data has been provided, configurations can be created.

Implementing FBT require usage of AddSearch API or JavaScript libraries:

• Search Client
• Search UI library
