As mentioned, the OR-Operator specifies Subphrases. As such, you aren't limited
to single words in the Subphrases. It could be something like: “angel of the Lord
| angel of light”. This would match either “angel of the Lord” or “angel of
light”.
You can also have as many OR-Operators within a Search Phrase as you desire.
For example, if you wanted to find “Peter” or “Paul” or “Mary” or “John”, you can
simply enter: “Peter | Paul | Mary | John”.
Don't worry about forgetting all of this while you are using the program. Just
hover over any Search Phrase and a Tool Tip will pop up to help you out:
