Can I set an unlimited length for maxJsonLength in web.config?

I am using the autocomplete feature of jQuery. When I try to retrieve the list of more then 17000 records (each won't have more than 10 char length), it's exceeding the length and throws the error:

Exception information:

Exception type: InvalidOperationException

Exception message: Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property.

Can I set an unlimited length for maxJsonLength in web.config? If not, what is the maximum length I can set?

The MaxJsonLength property cannot be unlimited. It is an integer property that defaults to 102400 (100k).
