I tried the Bing HTTP API and test the boundary case.
I got Bad Request Exception due to the query text is too long.
But I cannot find any document that describe the request string length.
I use English string for test and find the limit string length is 512...
But use Chinese or other non-English string can over 512.....
I used Encoding.UTF8.GetBytes(s).Length to get the byte information.
s is Chinese string.
It's over 512.
But didn't get bad request.
Could anyone give me some advice?
