Searching within corpus

[mzarozinski]

from David Smith: I created a new tag, "slave narrative", and tagged five pages. As it happens, two are duplicates of each other, and the other three are duplicates of each other, but I don't think that should matter. Anyway, I then did a "Search Corpus" for "canada" and another search of "helmsley". In both cases, the search returns all five pages, even though there terms appear on only one or two. I could imagine "canada" in the metadata for some books, but not all.
