Search Query report:
In the web interface, after selecting the appropriate campaign/adgroup, you can find it under the Dimensions tab, selecting View: Search terms. You can then download that as a report by clicking the little icon (arrow pointing into a tray).
I'm not sure the Dimensions tab is there by default, so you may have to enable it.
You can see the report in the interface or you can download it for further manipulation.
