Not all OCI resources returned by ResourceSearchClient

[lez-doit]

I am trying to load the list of all resources that are present in specific OCI deployment:

AuthenticationDetailsProvider provider = SimpleAuthenticationDetailsProvider.builder()
                    .tenantId(credentials.getTenantId())
                    .userId(credentials.getUserId())
                    .fingerprint(credentials.getFingerprint())
                    .privateKeySupplier(new StringPrivateKeySupplier(credentials.getPrivateKey()))
                    .region(Region.valueOf(credentials.getRegion()))
                    .build();

            @Cleanup ResourceSearchClient searchClient = ResourceSearchClient.builder().build(provider);

            String query = "query all resources";

            SearchResourcesRequest request = SearchResourcesRequest.builder()
                    .searchDetails(
                            StructuredSearchDetails.builder()
                                    .query(query)
                                    .build()
                    )
                    .build();

            SearchResourcesResponse response = searchClient.searchResources(request);

            for (ResourceSummary resourceSummary : response.getResourceSummaryCollection().getItems()) {

the response contains a lot of resources from the OCI, but not all of them, because I fail to match some resources I can see in UI to the list of records from API. I wasn't yet able to define if there's any pattern between resources that are not retrieved from API
