@S Feld I am less sure about making it run every 30 - 60 minutes.
However, you can have the results of a search be sent to an email of your choosing, here's how I do it.
1. create the serarch
2. once on the results page click 'Save this search'
3. On the next screen, you should see an 'Email' subtab. From this tab you can set where you want the results of the search to be sent and the format of the results.
Hope that helps.
