Update [2024-11-29]

The test cases related to content search and store visibility are failing.

Since the default setup's existing behavior should not be modified, any relevant changes should be implemented in the code, not in the tests. These functional modifications are being tracked separately.

Therefore, the plan is to revisit and validate the tests once issue #3406 is resolved.

Update [2024-12-06]

Same set of integration tests are failing even after implementing the unified search.
Hence double checked the following tests flows manually :

1. ContentSearchTestCase.testDocumentContentSearch()

• create a tenant and create & publish an API logging in as the tenant admin (no visibility restrictions). Add a documentation with github4156 in the content. Go to devportal and do a content search in the tenant's devportal providing the value github4156 (not logged in). No documents getting listed. But can see the document and the content when click on the API and go to the documents section.

  tested this in a pack without config and APIM 4.4.0 live pack as well. There also the same issue appears.

2. APIVisibilityByRoleTestCase.testVisibilityForAdminUserWithAdminAndSubscriberRoleInSameDomainInStore()

• create and publish an API from publisher portal. add role based visibility for admin. Login to devportal as admin. When click on the listed API it navigates to a not found page.

  This issue is not there in 4.4.0 live pack.

  Further analysed the issue. As the fix, the org visibility check should be avoided for super admin here: https://github.com/wso2/carbon-apimgt/blob/9d8bb3da0f71ac62c91feac96dc65bdf4daeb400/components/apimgt/org.wso2.carbon.apimgt.rest.api.store.v1/src/main/java/org/wso2/carbon/apimgt/rest/api/store/v1/impl/ApisApiServiceImpl.java#L1181

3. APIVisibilityByRoleTestCase.testVisibilityForCreatorInStore()

• Manually tested the following criteria which is given in the description. it worked as expected :
  Although API visibility on the devportal is restricted (eg, to the 'admin' role), if a user has the

   * 'internal/publisher' role, the API should still be visible to them.
   * This ensures that publishers can view all APIs of the organization on the devportal 
  

  Hence need to check this further

Added the fixes for the identified bugs, in separate commits in the PR : wso2/carbon-apimgt#12717
The previously mentioned secondary user store related issues require further investigation and resolution.
