In many of the guides you have the option to "Search all" of a particular resource type. For example, I can "Search all Systematic Theologies" or "Search all Grammars."
When I do this I get a new search window with the search field already populated.
Something like "<BibleESV Hebrews 1:8>" where the search criteria is "All text in All Passages in All Systematic Theologies" for...
However, when doing this some resources that have references to Hebrews 1:8 and are classified in my library as systematic theologies do not appear in the results. For example, Grudem's second edition ST.
If I search the resource directly for Hebrews 1:8 I get multiple hits.
Can someone please explain to me why this is the case?
