You can definitely use a projection. If you notice when you use the search function on the page you referenced, the inputs are formed into query string values. You can use tokens to grab the values from query strings to use in your projection filter.
For example, if you're using fields as you stated, then you just add a filter for that field and in the value field use {Request. QueryString:State}. Or, replace "State" with whatever key you're using for the query string value.
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.
