I am trying to pass the "defaults" options of "defaultFTSFieldOperator" and "defaultFTSOperator" to the search API and each time I include defaults, I get an error from Alfresco. I am not sure if I am providing them wrong or if there is an issue with passing these to the server in Alfresco 5.2.0. I have tried using curl as well as ADF(2.4) to pass the request and both have the same issue. I have also tried on two different servers running 5.2. I can provide more information as requested/necessary.
