The AsOf operator works with a date object to test whether an expression will yield result after a certain date position
Example:
- logicService.parse("'CD4 COUNT'").asOf(Context.getDateformat().parse("2009/12/04");
The above will give us a criteria to check if there's "CD4 COUNT" observations as of 12/04/2009
