--- title: Use the Relevance Generative Answering component slug: latest-atomic-rga canonical_url: https://docs.coveo.com/en/atomic/latest/usage/atomic-rga/ collection: atomic source_format: adoc --- # Use the Relevance Generative Answering component The `[atomic-generated-answer](https://docs.coveo.com/en/atomic/latest/reference/components/atomic-generated-answer/)` component lets you use Coveo's [Relevance Generative Answering (RGA)](https://docs.coveo.com/en/n9de0370/) feature to automatically generate answers to users' [queries](https://docs.coveo.com/en/231/). > **Important** > > You must [create your RGA model](https://docs.coveo.com/en/nb6a0085/) and associate it with a [query pipeline](https://docs.coveo.com/en/180/) before you can use the `[atomic-generated-answer](https://docs.coveo.com/en/atomic/latest/reference/components/atomic-generated-answer/)` component. The generated answer panel includes the following features: ![Example generated answer panel | Coveo RGA](https://docs.coveo.com/en/assets/images/coveo-platform/rga-panel-example-atomic-3-33-plus.png) [cols="2"] |=== |1 |The title of the [RGA](https://docs.coveo.com/en/nbtb6010/) panel. |2 |Clicking **Dislike** brings up a modal which asks the user to specify why they didn't find the information helpful. |3 |A **Copy to clipboard** button. |4 |A toggle to hide or show the [RGA](https://docs.coveo.com/en/nbtb6010/) panel. |5 |A disclaimer that advises the user to verify important information in the generated answer. |6 a|Citations highlight the [items](https://docs.coveo.com/en/210/) that contain the text segments ([chunks](https://docs.coveo.com/en/n9de0370#chunking)) that were used to generate the answer. Hover over a citation to view the chunk, or click a citation to open the item. An HTML item opens at the exact location of the chunk, which appears highlighted. > **Notes** > > * Set `[disableCitationAnchoring](https://docs.coveo.com/en/atomic/latest/reference/components/atomic-generated-answer#properties)` to `true` if you want items to open without pointing to the chunk location. > > * An item may appear more than once in the citations if different chunks from the same item were used to generate the answer. |=== ## Implement the RGA component In the search page HTML, add the `atomic-generated-answer` component to the `main` layout section. You'll probably want to place it before the `status` layout section, if present. ```html <1>

``` <1> For the [Atomic](https://docs.coveo.com/en/lcdf0264/) [RGA](https://docs.coveo.com/en/nbtb6010/) component to work, your search interface must use the pipeline with which the [RGA](https://docs.coveo.com/en/nbtb6010/) [model](https://docs.coveo.com/en/1012/) is [associated](https://docs.coveo.com/en/nb6a0104/). You can do one of the following: * Set the [search hub](https://docs.coveo.com/en/1342/) on the [`atomic-search-interface`](https://docs.coveo.com/en/atomic/latest/reference/components/atomic-search-interface/) component, as shown in the example. Then you need to set up [condition-based routing](https://docs.coveo.com/en/1666#condition-based-routing-recommended). > **Important** > > This is the recommended approach. * Omit the `search-hub` property and use [search interface-enforced routing](https://docs.coveo.com/en/1666#search-interface-enforced-routing) by setting the `pipeline` property. This example produces the following search page: ![Example search page with generated answer | Coveo RGA](https://docs.coveo.com/en/assets/images/coveo-platform/rga-search-page-example-atomic-3-33-plus.png) > **Important** > > If your search interface includes a sorting option, [Relevance Generative Answering (RGA)](https://docs.coveo.com/en/nbtb6010/) works best when results are sorted by relevance, which is the default sorting option. > Otherwise, an answer may not be generated. > > ![Search page sorting option | Coveo](:https://docs.coveo.com/en/assets/images/leverage-machine-learning/rga-relevance-sorting-option.png) > For more information on the reasons why an answer wouldn't be generated, see [When is an answer not generated?](https://docs.coveo.com/en/nb6a0008#when-is-an-answer-not-generated). ## Use an expandable search box After you implement generative answering, your users may begin to use longer [queries](https://docs.coveo.com/en/231/). Enable the `textarea` property on your [`atomic-search-box`](https://docs.coveo.com/en/atomic/latest/reference/components/atomic-search-box/) component so that it can expand to support multi-line [queries](https://docs.coveo.com/en/231/). ![Expandable search box | Coveo RGA](https://docs.coveo.com/en/assets/images/coveo-platform/rga-expandable-search-box-atomic.png)
