The first time you log in to DeepResearch, you will be taken to a page to select resources over which you'd like your searches to run. By default, all are selected. Use the checkboxes to create a custom set, which will be used for all subsequent searches and alerts.
If you'd like to change your custom set of sources, you can come back to the source selection page by:
- Choosing "Edit sources" within the advanced search page
- Choosing "Source setup" from the gear menu on the results page.
"Limit to source" is also a filter available within search results; selecting/deselecting sources here does not change your underlying custom set.
