By default, all query rewriting strategies are enabled, and all of the data in the
_query_rewrite_staging collection is applied in the Simulator. To see how relevancy is affected by individual strategies, you can selectively enable or disable strategies in the query rewriting dashboard.
From the Simulator, click Query Rewriting Dashboard.
The query rewriting dashboard appears:
Click Enabled to disable an active strategy, or click Disabled to enable an inactive strategy.
Click Simulator to return to the Simulator and see how your changes affect search results.
