I found that this restriction is not a restriction, but a setting - and it can be changed! Go to Central Administration and then go to:
- Application Management> Web Application Management.
- In the list of web applications, select the desired web application.
- Then go to General Settings> Resource Throttling.
- In the Resource Management window, scroll down to Attempt to View List and change the value to a number that matches your needs.
Of course, increasing this value affects performance because there is more drilling through SQL tables, so be careful not to go too far. And one more thing: changing this value affects not only the list views, but also changes the behavior of methods that work with list items. For instance. if this parameter is set to 8, this will return a maximum of 8 search fields for the list item when GetListItems (request); (Customer Object Model). Increasing this number, say 15, will increase the maximum number of returned search fields for a list item. Pretty neat!
