ok but the second solution has same performance or not?
pratically query-times join work making nested query:
execute first query
then for every row it execute the corrisponding row in the secondat table
using foreign key and primary key ?

I don't see any reasons why it couldn't work in this manner. but it just
usually slow.

Query-time joins
String fromField = "from"; // Name of the from field
boolean multipleValuesPerDocument = false; // Set only yo true in
the case when your fromField has m

Have other more experienced comment though before you start implementing it.
