Step 3: Select the Email Addresses Query
In the Query Library window, find the Query named “Email Addresses“. Highlight this query by clicking on it. Then click the “Select” button at the bottom right hand corner of the Query Library window. This will configure Power Search with all the necessary settings. (The “Query” field should now contain “(?[a-z0-9\.]*@[a-z0-9]*\.[a-z0-9\.]*)” (without quotes) and the “Regular Expression” Query Type should be selected.
