# Cardinal Placement for Documents

QMS can place selected documents at certain positions in a results list, regardless of document relevance or other factors. For example, you might want a certain car advertisement to be the first result at all times for the query “sports car”. Cardinal placement can ensure that this placement occurs.

QMS forwards all queries to IDOL Server or the Content component to retrieve results. It also forwards the queries to the Promotion Agentstore component, which returns any cardinal placement rules for the specified query. When QMS receives the results, it inserts any cardinal placement documents at the correct position in the results list before it returns results to the client.

QMS moves the cardinal placement document to the correct position if it already exists in the result list from IDOL Server.
