Large log messages created when there are invalid characters in the query string

Cause: in Go Green, when the search is performed after giving an invalid path in the URL, the query string is not escaped. (An example of a search that way is: http://www.demo.test.onehippo.com/solar ).
Some of the characters for which this happens: [ ' ( ) "

This might also be a security issue, equivalent to SQL injection.

To reproduce, using Go Green test server:

• Go to: http://www.demo.test.onehippo.com/abcd) (including the closing bracket)
• Check the cms log

For every such request, more than 20kB of log messages are created. The result of a single request is attached. (logs.txt)
This way, a malicious user can fill up the logs quickly (50 requests = 1MB)
