Is it possible to use a wildcard in an IIF statement

I have a generic inquiry that I am using an IIF statement in the Results Grid to add and populate a column in the GI results.. 

The statement is as follows:

=IIf( [SOInvoice.DocDesc] = 'ROLLER', '050116', ' ' )

What I am running into is there have been a few time where the SOInvoice.DocDesc containers more than just “ROLLER”, it might have ROLLER - xyz. 

When the GI is run this field is empty if the parameter of ‘ROLLER’ isn’t exact. Is there a wildcard available in Acumatica like the * in VB?

Thank you!
