I need to mark a few indexed columns in a set of libraries and have only been able to accomplish this on the smaller ones.  Two are now about 1.5 million and 5.2 million documents (and growing, of course).  When I try to mark a column as indexed the process times out and does not complete.

 

I need to either remove this timeout or find a way to make an indexed column from the command line.  Anyone have any suggestions?

 

Thanks!
