Zoho Projects API - Searching Projects by Custom Field

Hi

How can I search all projects by a custom field?

I can confirm that using the search_term parameter as documented here does not work for me:

https://www.zoho.com/projects/help/rest-api/search-api.html#alink3

My search term is "22424", which corresponds to a value in a custom field in the project ("Stock ID").

My GET:

https://projectsapi.zoho.com.au/restapi/portal/7001048748/search?search_term=22424&module=projects

This returns no results.

Any possible reason this would fail?

However, searches for terms contained in the name of the project do return results.

Thanks.

Marcus.
