The cause for is that when parsing the DQL Doctrine won't recognise `ILIKE` as a known operator. In fact `ILIKE` is registered as a boolean function.
 Doctrine doesn't provide easy support for implementing custom operators. This may change in the future but for now it is easier to trick the DQL parser with a boolean expression.
 
 Example intent with DQL:
