Assume that you execute a full-text query that uses an execution plan that includes parallelism over full text operator. You set a condition that causes this query to execute serially at run time by using this execution plan. In this situation, the query result is incorrect.
For example, consider the following scenario:
You enable the Resource Governor in a Microsoft SQL Server 2012 instance.
You create a workload group and set the value of the Degree of Parallelism option to 1.
You execute a full-text query that uses a MAXDOP query hint that the value is larger than 1 through the given connection.
In this scenario, the query result may be incorrect.
