It's good practice to save your search criteria. This allows you to re-run the search at a future date to generate a new updated list.
Step 1. To edit a saved search you first have to open it by clicking its name.
Step 2. At the top of the results page, click on the link to "Edit your original search".
The search criteria that you set up previously will now be available for edit and you can make any changes you require.
Remember that you can monitor the number of contacts your search towards the bottom of the page where it says "Save and View n Results".
Step 3. Once you are happy with the changes you've made to the search criteria, you can now save the search, overwriting the previous search criteria, and view your results.
Important: If you would like to edit a saved search but keep the current version intact, you will first need to make a copy of it. To do this, you'll need to selecting the saved search from your list of saved targeting searches. Check the tick-box next to its name. Once selected, go to Actions and click on "Copy Selected".
Click "Copy" in the pop-up window.
In your list of saved targeting searches, you will now see the new file with with "Copy1" appended to its name. You may need to refresh the browser page in case the copy is not yet showing on your list.
You can now edit the saved copy without worry of overwriting your original saved search.
