Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Check if response code from GGInA is 200 OK Only parse the GGInA response if the status code is 200 OK. This improves the error message if GGInA is not available and shows the real reason instead of a JDOM error while parsing the response.
