Sometimes I need to be able to pull a query based on a unique value that may include more than 500 values.  For example, I have a list of students from a specific time period that was provided with student ID numbers (not constituent IDs).  I copy/paste their student ID's and add them to a query using the One Of operator in order to pull the list I need in Raiser's Edge.  I often have more than 500 students on a list and the One Of value limit is 500 when copying values in.  It would be nice if this limit was removed and it could be unlimited or at the very least be up to 15000 values.
