A query set is silently rejected without a reason on the screen or in the log when a composite index specifies a value not in the query set.
Upon refreshing the query set configuration files when a composite index has a field that is not defined in the properties nor in the aspects of the query set an InvalidQuerySetConfigFileException exception is thrown which is then caught in RqaQuerySetMBeanImpl::refreshQuerySets an appropriate error message should be logged but since logs are not activated for the class we do not see anything.
The error we should see looks like this:
01240021 composite-index 'index_1' references undefined field: cm:author
As a result of the above the error message that is shown in the admin console is:
Invalid query set configuration file.
I believe this messages should be more specific too.
