Options for Downloading Data:
  Using Firefox as your Browser: once search is run, you can filter the results using the Filter JSON option 
  (see top right of your screen). (Chrome does not have this feature automatically, you would need to add an extension).
    simply type in text string like 
    alcohol or perhaps just a partial string like alc 
    and the software will limit the recordset to only records with the string you entered.
Once search is run (using any browser), you can download the data (in JSON format).
