# Link projects for cross-project search
Before you can search across multiple projects, you must link them together. Cross-project search only works between projects that are explicitly linked within your Elastic Cloud organization.
This guide explains how to link projects in the Elastic Cloud UI so you can run cross-project searches from an origin project. For an overview of cross-project search concepts such as origin projects, linked projects, and search expressions, refer to [Cross-project search](https://www.elastic.co/elastic/docs-builder/docs/3028/explore-analyze/cross-project-search).

## Prerequisites

- Cross-project search requires linked projects.


## Link projects using the Cloud UI

You can link projects by using the Cloud UI.
1. On the home screen, select the project you want to use as the origin project and click **Manage**.
2. Click **Configure** on the **Cross-project search** tile. Or click **Cross-project search** in the left-hand navigation.
3. Click **Link projects**.
4. Select the projects you want to link from the project list.

1. Click **Review and save**.
2. Review the selected projects. If you are satisfied, click **Save**.

When your configuration is saved, a page with the list of linked projects opens.
