API v2 operator "NOT IN"
Hi Lithium, When can we have this function for the API v2? For example, Customers would like to query all messages except for few boards. Peter

You can achieve this by custom freemarker function. Firstly you can store all the boards IDs that you do not want to show in a freemarker array. Please see below code:
<#assign boards_id = ['board_id_1','board_id_2','board_id_3'] />
After that you can make a rest api v1 or v2 call to fetch all messages and run through loop and also check if the board id exists or not. In my case I am using V2 call. See below code:
<#assign messages = rest("2.0", "/search?q=" + "select * from messages"?url).data.items />
<#list messages as message>
<#if !boards_id?seq_contains(message.board.id)> <!-- checks if board id is not in mentioned IDs array -->
<!-- display message's content other than boards you do not want to show -->
</#if>
</#list>

him_varma, your code won't work in a pagination environment. And it won't work in some situations as well. NOT IN solution is the ultimate way just like the good old database days.
If we achieve this through custom functionality then we certainly be handling the other cases through custom functionality only. We can build custom pagination using an endpoint to fetch results page wise that will have the same logic as I mentioned above.
As long as we do not have the NOT IN operator we could use customizations to achieve the desired functionality :)
