Configure a search interface for Relevance Generative Answering (RGA)

This is for:

Developer System Administrator

To leverage Relevance Generative Answering (RGA) in your search interface, you must enable the RGA component for the search interface.

The RGA component adds the RGA question-answering experience to your search interface. For more information, see RGA component features.

Note

To generate answers you must associate an RGA model to the query pipeline that’s used by your search interface.

Important

If your search interface includes a sorting option, Relevance Generative Answering (RGA) works best when results are sorted by relevance, which is the default sorting option. Otherwise, an answer may not be generated.

Enable the RGA component

You can enable the RGA component for the following Coveo search interfaces:

Hosted search page

If your search interface was created using the hosted search page builder, enable the Relevance Generative Answering option in the builder to add the component to your search interface.

Notes

  • The RGA component appears at the top of the search results page.

  • RGA isn’t supported in hosted search pages created using Coveo JavaScript Search Framework.

Note

The RGA component appears at the top of the search results page.

In-Product Experience (IPX)

To add the RGA component to a next-gen In-Product Experience (IPX) search interface, enable the Relevance Generative Answering option in the builder.

Notes

  • The RGA component appears at the top of the search results page.

  • RGA isn’t supported in classic IPX search interfaces.

Coveo Atomic search page

If your interface uses the Coveo Atomic library, the interface must include the atomic-generated-answer component.

Tip

Coveo recommends that you use the textarea property of the atomic-search-box component to make the search box expand to support long queries.

Coveo Headless search page

If your interface uses the Coveo Headless library, the interface must use the GeneratedAnswer controller.

Coveo Quantic search page

If your Coveo for Salesforce interface uses the Quantic library, the interface must include the QuanticGeneratedAnswer component.

Tip

Coveo recommends that you use the textarea property of the QuanticSearchBox component to make the search box expand to support long queries.

RGA component features

The RGA component adds the Relevance Generative Answering (RGA) experience to your Coveo search interface.

RGA integrates generative AI question-answering with traditional search. A single search box supports both simple and complex natural language user queries, and provides both traditional search results and a generated answer.

When a user enters a query, RGA generates the answer in real time on the search results page. If the user then applies filters to narrow down the search results, the answer regenerates on-the-fly based on the selected filters.

The RGA component adds a dedicated area to your search interface that’s used to display the generated answer and other RGA-specific user features.

Note

User interactions with the RGA component are logged as Relevance Generative Answering (RGA) UA events.

The answer that’s generated by RGA.

2

Users can click a feedback button to log whether they liked or disliked the generated answer. When clicking the thumbs-down icon, a dialog appears that asks the reason for the negative feedback.

3

A copy button lets users copy the generated answer to their clipboard.

4

Users can choose to show or hide the RGA component in their search interface. RGA still generates an answer for a user query even when the component is hidden. In this case, showing the RGA component reveals the generated answer.

5

Users can select one of the rephrase options to format the generated answer as a numbered list, a bulleted list, a brief summary, or have RGA automatically choose the format that’s best suited to the query. Users can switch between formats for a given answer.

6

Citations highlight the items that contain the raw data that was used to generate the answer. Users can click a citation to open the item, or hover over a citation to view the specific item chunk that was used to generate the answer.

An item may appear more than once in the citations if different chunks from the same item were used to generate the answer.
