If you are using SharePoint 2010 you must also add a new managed property to your search application. If you are using SharePoint 2013 this is not necessary.
To create a new managed property, open your Search Application in the Central Administration and click on Metadata Properties.
Then click on New Managed Property.
Enter the name ListItemID (case-sensitive) and select Integer as the type of information.
Then click on Add Mapping, look for ows_id and select it.
Confirm with OK.
After you have added the property, you must run a full crawl.
After the full crawl has been completed, the error should disappear.
If the error still occurs, make sure the “Max. size for Search Results (rows)”, which can be set in the web part configuration, is not too high. This value should be between 500 and 10,000. If the number of items returned exceeds the configured limit, a message will be appear on the screen. The message is “Warning: Searching for ‘keyword’ returned more than n items. Please use more specific keywords or operators (AND, …) in your query.”.
