To ensure I was understanding how openFDA works, I have been checking my queries against the searchable medical device recall database the FDA already has (http://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfRES/res.cfm). I am currently trying the following query: https://api.fda.gov/device/enforcement.json?search=insulin&limit=80 and getting 56 results back. A similar query at the FDA database simply searching for "insulin" in product description gives back 117 results.
I understand that some of the newest device recalls will not be in openFDA yet, but I can't figure out why others are missing. For example, a recall for "OneTouch(R) Ping(R) Insulin Pump glucose management system" posted April 6, 2012 with event ID 61436 found on the FDA database is not in openFDA. I have tried searching by event ID in openFDA as well as searching by name and it's not showing up. I have found other examples as well from 2009
What am I missing here? Why don't these show up in an openFDA query for "insulin?"
