      Description

      This can be accomplished using the collMod command. The syntax for changing the value of the expireAfterSeconds field is:

      db.runCommand( {"collMod" : [collection] , "index" : { "keyPattern" : [indexPattern] , "expireAfterSeconds" : [newVal] } } )

      For instance:

      db.runCommand( {"collMod" : "foo" , "index" : { "keyPattern" : {a : 1} , "expireAfterSeconds" : 3600 } } )
