Filter substringof and top parameter cannot work together in Resources#List

[ArcturusZhang]

When I call rest api

/subscriptions/${subscriptionId}/resources?$top={top}&api-version=2018-05-01&$filter={filter}

and filter contains a clause of substringof, then the top parameter will be ignored.

To reproduce:

I used Postman to send this rest api request. Armclient or az CLI cannot get the filter in this request to work. I filed another issue about this in the armclient repo.

Use postman and call GET

https://management.azure.com/subscriptions/${subscriptionId}/resources?$top=2&api-version=2018-05-01&$filter=substringof('test', name)

Expected behaviour: Getting a response with 2 entries with name contains test in them and a nextLink for a url that I can fetch rest part of the full result list.

Actual behaviour: Getting a full list of filtered resources, as if the top parameter get ignored.

If I replace this filter with another one without substringof clause, the top parameter works fine.

Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc @armleads-azure.

@ArcturusZhang - Not sure how no one looked at this yet but here I am 😄 I see that this issue still exists even in the new api-version so I'll add this to our backlog to address.

Any update for this issue?

Hi @DeloitteAnwarBashaP , while investigating this issue previously, we ran into a conflict with how resources are queried, which prevented the proper number of resources from being returned. Because this is a design constraint, the observation is to be expected, and the relevant documentation for this API has been updated with the following note: Note that any truncated number of results queried via $top may also not be compatible when using a filter.
