I want to build a query by concatenating text, conceptual similar as:

FIND Project WHERE Project.projectUitvoerders CONTAINS ',' +LoggedInRegularUser.LoginName + ','

"projectUitvoerders" is a PlainText field containing usernames separated by a comma (',').

But seems the concatenate doesn't work, I get an SQL syntax error (username = 'awareim'):

WebServlet URL got request with params:

So, I've two questions:

1. How could I use a concatenate in an Aware IM query? I need also to be able to pass the context (logged-in username) to my query.
1. How can we add extra logging to see the exact SQL-query that is generated by Aware?
