Diana,
Thanks for the excellent feedback.
I modified the plugin, and it now supports what you’re asking for.
If you’re using the widget, just wrap everything in quotes in the ‘query’ field. For example, “search term site:scholar.google.com”
If you’re using the shortcodes, you just have to be careful with how you wrap the quotes. For example, if you wanted to search for an exact phrase (let’s say Android sales), and you only wanted results returned from Engadget, you would do this:
[google_news query='”android sales site:engadget.com”‘]
If you run into any problems with this, please let me know.
Thanks!
Kevin
