how can we search 2 values in a column().search() / exclude a value from search?

ASL

Hi there
I am trying to search 2 values in a column through the below way..

dataTable.columns(7).search("Completed|Pending",true).draw();

Also how can i search a column for all values except a particular to get displayed?

All my search values are coming from my url parameter - So i dont know how to pass them to the table generally.

But this does not seem to work.
Any alternative?
