The default Smart Lookup configuration is to show US exchanges first in the output results and then Canadian exchanges.  We have limited support to exclude specific exchange codes  Smart Lookup outputs results for exchanges based on the WMID level entitlements and does not check entitlements at the user level.  Expired symbols are excluded from the results.

The search results are based on exact match first and then a secondary order can be applied in our configuration files to order by specific exchanges.
