Delegable IN operator for Sharepoint Lists

[t3ddy]

Please add the IN operator as a delegable function for SharePoint Lists, because there is actual no alternative to search for a substring in big SharePoint Lists (>100000 items).

As SharePoint is SQL based, this would be no problem to implement ... and a major improvement for users in filtering galleries. 👍
