Bug 37249: Disambiguate itemnumber with USING clause

Bug 37249: Disambiguate itemnumber with USING clause

1. Do an item search that returns results
2. Use the column filtering available at the top of the table for each column
3. Try itemnumber, get a 500 error each time
4. As long as there is data in the itemnumber column and you attempt to use another column you'll see a 500 error.
5. APPLY PATCH, restart_all
6. The itemnumber column filtering should now work as expected
