combine cannot be longer than 128 characters but is currently 275 characters long

Hello,

I am trying to expose to users a "combine fields filter" whose operator is "Contains". Also, I am using "views autocomplete filters" module, in order to show to the users all the fields that contains a certain word. The issue is that my fileds can have until 500 characters long, so I have got the following error when I push submit button or reset button: "combine cannot be longer than 128 characters but is currently 275 characters long".

Which one is the best way to fix this? (little knowledge of php.)

Thank you for your attention (it is important).
