Add Documentation for the CONTAINSANY operator

[creisle]

Currently missing documentation for the CONTAINSANY operator which should be added to the list of possible operators

@luigidellaquila I am looking at adding this myself, should be pretty trivial except that I am unsure since when this feature was available. Do you know? Also I can't assign myself an issue

Also would it be possible to add examples outside the table? I'd like to add some more clear examples but its difficult to do in the table form. Could I add an examples section to the SQL-Where doc? and then link to that from the table?

Hi @creisle

Sure, we can consider it. I'll try to do it asap

Thanks
