      Suppose you have documents that look similar to this:

      { "PRE-field1" : "value",  "PRE-field2" : "value", "PRE-field3" : "value"}

      Fields in a document may start with "PRE-" and have any characters after that. During the projection stage, I want to be able to project all fields that contain the string "PRE-". Maybe the project statement looks something like this:

       "$fieldNameSearch" : /.*PRE-.*/i
