  the LIKE query matches rows that contain terms such as "linuxophobe"
  or "EnterpriseLinux" (as it happens, the Enron E-Mail Dataset does not
  actually contain any such terms), whereas the MATCH query on the FTS3 table
  selects only those rows that contain "linux" as a discreet token. Both 
  searches are case-insensitive. The FTS3 table consumes around 2006 MB on
  disk compared to just 1453 MB for the ordinary table. Using the same
  hardware configuration used to perform the SELECT queries above, the FTS3
  table took just over 39 minutes to populate, versus 25 for the ordinary
  table.

  Check if the numbers are still valid using the refactored version.
