The search box  is found at the top of Find.  It performs ‘smart searches’ by pulling all scans related to what is typed in.  If you don’t know the name of the specific scan, but know it is related to Earning  announcements, type “earning” and a list will populate showing scans that are about Earning.  Typing  “Bull” or  “Bear” will bring up scans with  “Bull or Bullish” or “Bear or Bearish” in their names, respectively.

Of course, you can also elect to search by clicking the arrow for a complete list of available scans in a drop-down search.
