Unable to Get Search Results in Vertex AI Search App Preview

[pinata]

Please help me.

No matter what I search for in the Vertex AI Search app preview, I always get the message:
“No results found. Try changing your search terms.”

The strange thing is, other members in the same organization can search just fine — I’m the only one experiencing this issue.

There are no console or network errors, and my IAM and Datastore permissions are identical to the members who are not facing this problem. I’ve tested various scenarios, but the result is always the same: no results.

Here’s what I’ve tried so far:

・Logged into an account that can search normally and tried the same queries

・Searched using a mobile tethering connection

・Tried both macOS and Windows

・Followed the Vertex AI Search tutorial — it worked only on Windows. On macOS, a 403 error occurred during the search

Any advice or suggestions would be greatly appreciated.

Hi @pinata,

Welcome to the Google Cloud Community!

It looks like you are encountering an issue where the Vertex AI Search app preview consistently returns a "No results found" message, despite other members in your organization being able to search without any problems.

Here are the potential ways that might help with your use case:

• Confirm IAM Permissions: You can utilize the IAM Policy Troubleshooter to verify whether you have the required Discovery Engine search permissions for a particular Datastore or serving configuration.
• Correct Project: Make sure you are working within the same GCP project as your colleagues when accessing the app preview, and verify the project ID in the URL.
• Use a different browser or clear your browser cache: You may want to try using a different browser or clearing your cache and cookies, as the 403 error appearing on macOS but not on Windows suggests a potential issue with stored data or browser compatibility.

Thank you for your response!
I tried it out right away.

• Confirm IAM Permissions: I used the IAM Policy Troubleshooter and couldn’t find any specific permissions for Discovery Engine search, so I tested with discoveryengine.{conversations|engines|models} permissions like get and create, and it showed that the permission policies were granted. However, I couldn’t determine other factors such as principal access boundaries, deny policies, or final results.

• Correct Project: It was the correct project!

• Use a different browser or clear your browser cache: I tried using Safari and also cleared the cache in Chrome, but the result remained the same. Additionally—this part is a bit tricky—previews created by the organization display “No results found” on both operating systems. However, the Vertex AI Search tutorial only returned search results when tested on Windows.

If you have any further suggestions or ideas, I’d really appreciate your input!
