Understanding Search Results

• The list of leads returned by a search will show 'Workflow' and 'Task/Event' labels to highlight that the lead has an active workflow and/or a Task/Event
• Clicking on the lead ID will open up a pop up box containing more details of the lead, and the full date/time received. The '+' icon to the right of each lead in the list opens up the lead summary 'quick view' which allows for carrying out actions such as sending an email or creating a task without leaving the search leads screen. Clicking the view record icon navigates to the lead summary.
• Sub leads are also displayed in the search results, and will appear under their parent lead (if the parent lead is included in the list). A sub lead can be identified by it's hyphenated ID, in the format 1000000-1000 (lead ID 1000000, sub lead ID 1000).
• It's possible to click on the column headers to sort search results by that header.
