The system automatically caches your last search term and connects it to your contact record.  If you would like to prevent the same term from showing up every time you navigate to the search:
  1. Go the section where the same search term populates by default.
  2. Delete the search term, so the box is blank.
  3. Select the search button.
Once completed it will be cleared and it will not populate automatically.  You can perform this after your searches so it will always populate blank if desired.
