When using "one of" in query, we can paste in up to 500 entries in the drop down list. It appears when using <ask> and then selecting "one of", the maximum number of entries is only 200. 

I have a simple query that I did a "one of" constituent ID - and put in up to 500. I then changed that query to be "ask". then when I run it, I select "one of" and try to paste in up to 500 ids - but the list gets full at 200.

Export using the query has the same 200 limit.

"one of" should always accept the same maximum number of entries no matter how it's selected.
