Hi, Daniel, and welcome to Accordance!
First, yes one of the features in 10 is that you don't need to worry about Verses vs. Words in your searches, it should switch for you if necessary.
Now then, regarding your specific error, I believe I know what is going on. If you look to the right of your Scope is Verse menus, there are the two arrows to the right. These indicate that you have an additional search condition set that isn't visible due to limited screen space. I wonder if this condition is set to Brackets, that they are Exclusive. This would prevent the BBE from finding Adam, as it is searching only within [bracketed words]. Just remove the condition or change it to Inclusive or Ignored.
Some quick explanation of all of the things I just talked about:
• The search conditions that you've added are very useful at times, but usually not needed except for certain types of searches.
• Accordance will always search [All Text] if there is no Range condition applied, so unless you want to specify a specific range to search, you don't need that condition up.
• The Scope condition generally only applies with compound searches. For example, if I want to find Adam and Eve within the same Verse, I use 'Adam <AND> Eve', with Scope set to verse. If I want to find those two words within the same Chapter, I then change my scope to Chapter. But, for a single word search, it doesn't really affect anything.
• The Bracketed Words condition applies when dealing with words between square brackets [ ] . Inclusive is the default, which means that searches search words both inside and outside the brackets. Ignored means that Accordance doesn't search the words inside the brackets, only the ones outside them. Exclusive is probably what was causing the error and means that it will only find words inside brackets. I imagine BBE doesn't even use brackets, so thats why Adam wasn't found inside of them.
Generally, I keep my search conditions all closed to maximize the space my text can appear, then I only add them as needed. Some users like to keep all three visible for easy access each time, which is fine of course. In your case, that hidden one was set to Exclusive and thus preventing your search. Note, in your case where its overflowing, the arrows are also a menu that lets you access the bracket options without having to make your window bigger.
Hope this all helps!
tl;dr: You appear to have a Bracketed Words condition set to Exclusive, which means it won't find Adam. Change that to Inclusive, or just remove the condition to fix your search.
