Where is the search box today?

In google, we were able to select a feed and search within the feed. I would like to be about to seach individual feeds and also have the option to exclude.

I am finding the search to be very challenging even at the basic level. Basic phrase searching does not seem to work, e.g. "Irving Berlin", nor do AND or OR Boolean operators. It makes it very difficult to find things. Am I missing something here? Having ability to facet and limit searches is nice, but I would love the basics to be working well.

I would really like to be able to search by keyword in the article descriptions as well as the title.

Add:
-Search by Keyword
-Search by Title
-Search by Author

Apologies if this is already available.
