You need not create a single combined field, keeping them separate is probably a better design decision. Think down the line, you might want to do specialized searching.
Using a single search field is the most efficient solution. This will make you index smaller and faster to search. Even if you stored fields, you could still have one single aggregated indexed (but not stored) field for search, and one stored (but not indexed) field for every contact information.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
