That's an interesting question.
If you search the database for ERA you see it occurred in the NYT on May 23, 2012.
Now according to magus' report of the LAT on May 1, 2012, the entry CEES appeared on that date. But if you search for it in the database, the most recent occurrence of CEES in the LAT is Feb 18, 2011. So the May 1 entry is not in the database.
It looks like different publications get updated in the database separately - the LAT is not as up-to-date as the NYT.
