I'm not sure of the terminology for this, but say, if you search for "Moses" in 'Everything' you'll get a lot more results from a lot more resources than searching for "<Person Moses>", because it seems certain resources, especially bibles, get much deeper tagging than other resources also classified as "Logos Research Edition." I'm especially desiring of being able to search the library for topics or preaching themes (e.g., seeing which resources cover <Topic Equality> instead of having to search for the word "equality").
I realize that the deep tagging of bible text is only possible because of all the hard work by hand that goes into these resources, so I look forward to AI (I'm sure AI has already been created that can parse language, CleverBot for example) being used to make for much richer tagging (and perhaps cross linking) of all resources, whenever that is possible.
I think I am not understanding how "Logos Research Edition" resources in general are more functional than "Logos Reader Edition" or "E-Book" editions when, if I understand correctly, most resources are mostly plain text only with links to scripture and limited cross referencing to other resources. On that note, I'd like to, say, find who mentions or references the sayings (in a block of text / passage in a resource) of an early church father like Irenaeus in like manner to being able to get a passage guide with detailed information on, say, John 3:16. I don't know of any guides or tools besides basic search that can work with / analyze resources in general besides bibles.
