I have a list that contains around 16000 items and will be growing. The List View Threshold is set to the default value of 5000 (SP 2010).
I have nothing to do with the SP list views and UI for this list and all I do with this list is query it using the ReST query with filters. The filtered query returns only a handful of items (at max 20).
The query was working fine until the count of item was less than 5000. But now it is returning Internal Server Error (HTTP 500) when I run the query.
Can someone help?
