REST API Query Parameter Or Condition

Content

Hi,

Below query parameters working fine.

/crmRestApi/resources/latest/contacts?q=FirstName=Mary;LastName!=Aiza 

The above condition acts like FirstName = Mary and LastName != Aiza 

But I want to use OR condition in query parameter

1. MobileNumber = 937937937 OR EmailAddress = john@test.com

2. (FirstName = John AND LastName = Smith) OR (MobileNumber = 937937937 AND EmailAddress = john@test.com)

How to achieve the above conditions in query parameters (Using Postman)?

Thanks,

Mohan
