With all the new searches, it's sometimes been tricky to compose the search criteria correctly.
Imagine you're looking for the times when Jesus speaks to Peter. You know it's {Speaker <Person Jesus>} and {Addressee <Person Peter>}. But do you use WITHIN, or ANDEQUALS? And if it's WITHIN, which one will be WITHIN the other?
Sometimes the results were the same. Sometimes they were different. You often ended up running searches multiple times to make sure you had it right.
Now, you can just use the new search operator - INTERSECTS, and every verse where the two terms overlap will be included:
{Speaker <Person Jesus>} INTERSECTS {Addressee <Person Peter>}
The nice thing about it is that you don't have to remember strategies to use it. It pretty much works in every situation where you're looking for two things (particularly phrases) to overlap.
