All data is indexed as keyword phrases in EBSCO EDS, rather than in bound-together phrases as in the library catalog title or subject indexes.
Here are some idiosyncracies for keyword searching.
Not all subdatabases index the “subjects” the same way.
This doesn’t find any ATLA Religion database entries, because Augustine’s works are all indexed under “Augustine…” not by the work
When you select an “authorized” form of the subject heading (by clicking the link in the record detail view), it may not be the one used in the other subdatabases:
ATLA databases use
The library catalog uses “Augustine, Saint, Bishop of Hippo”.
Also, the field designator from the link (DE for descriptor vs. SU for subject) can differ between databases.
Field specifications: “Select a field (optional)” searches all fields EXCEPT the full text. “TX – All text” searches the content of the full text of ebooks.
