[sword-devel] Search Types

[David "Judah's Shadow" Blue]

I've been doing more with searching in BIBISH for the upcoming 0.6 release,
and I've come across the various search types. I understand the multi-word,
exact phrase, and regex types. I assume the entityattrib type searches
attributes like lemas, strongs numbers, etc. But I'm uncertain what the
external search type is used for. Can anyone shed some light so I can decide
if I want to incorporate it into BIBISH?
