I noticed the Logos 7.4 release notes state
Added new Illustration paragraph type. After using illustration paragraphs, you can search your sermons for illustrations you’ve used. Search with “illustration:bike”.
Can anyone please explain exactly how to search your sermons like this? I don't see the option to search sermons in the main search window. Perhaps I'm missing something. Thanks in advance!
Do a Basic search on Everything or Your Documents, and you will get back results from your sermons and other documents.
