Pass Query parameters with "OR" condition during REST API GET Operation

Summary:

Hello,
I'm trying to do a REST API Call (ItemsV2) to get the list of items by filtering it in VBCS.

I have one input text binded to a variable(varArticleSearch). I want to be able to search by ItemNumber or ItemDescription.

My Q Parameter looks like this :

"ItemNumber LIKE \'*"+$application.variables.varArticleSearch+"*\' OR ItemDescription LIKE \'*"+$application.variables.varArticleSearch+"*\'"

But it's not working.

Is the operator 'OR' supported ?

Thanks in advance for your help
