## 💡**Prerequisite knowledge**



We recommend that you review the following guides to understand the algorithms discussed in this guide:

  • [Search Recall Precision](🔗)

  • [Spell Correct](🔗)

  • [Facet Precision](🔗)

  • [Query Relaxation](🔗)

# **What is the Algorithm Controls feature **



**Algorithm Controls** feature empowers you to control and adjust 4 of our algorithms directly through front-end API calls or Bloomreach's dashboard tool. You can modify the settings of the following algorithms:

  • Search Recall Precision

  • Query Relaxation

  • Spell Correct

  • Facet Precision

# **Why is this feature valuable for your business**



  • **Greater independence: **The Algorithm controls feature enables you to **customize and manage our intelligent algorithms**. The result is greater independence in choosing and implementing the configurations that best suit your business needs.

  • **More convenience:** With Algorithm controls, you get the flexibility to **modify our algorithms at your convenience**. You save time, effort, and overhead by not having to file Support requests for algorithm customizations.

# **How this feature works**



You can conveniently configure the Algorithm Controls feature using either of the two routes:

  • [API Controls](🔗): This route allows you to customize the algorithms by passing a specified parameter directly to the front-end API call.

  • [Dashboard Controls](🔗): This route enables you to adjust the algorithms directly from the Discovery dashboard.

# **How to enable this feature**



**Live Customers**: This feature will be enabled by default for all Search customers. **Integrating Customers**: This feature will be enabled for all currently integrating Search customers.

# **Limitations **



  • AB testing of these algorithm controls through the dashboard is not supported at this time.

  • Other algorithm controls like Lookup and Relevance by Segment are not supported.

# **General FAQs**



  1. **Is there an additional charge for a customer to get this feature?** No. It is available to all Discovery Search customers.

  2. **Does this feature support both Search and Category?** Currently, the supported controls are relevant only at a Search level. Category support will be provided in the future.

  3. **Does this feature support Pathways?** No.

  4. **What are the different ways a customer can AB test these Algorithm control features?** For AB Testing, you can use the following 2 ways:

  • **Backend configured AB tests**: You can contact Bloomreach’s business services to configure AB tests in the backend. However, while performing tests through the backend, it is recommended not to pass a different setting on the API

  • **Self-managed AB tests:** You can manage AB tests on your own because parameters are controllable through the front-end API. For example, you can just pass experience A with one type of precision mode and experience B with another type of precision mode.
