Hi 1) What is the principal difference between COST vs SCORE vs WEIGHT
2) Assume we have BooleanQuery with 5 TermQuery subqueries that are included via SHOULD condition. Assume we have 5 fields and one subquery is need to search in one field. Some product of MultiFieldQueryParser. In this case the score of BooleanQuery is the sum of scores of each subquery. I expected that not all subqueries will be included but only those who founded something, but in fact there is a sum of all subqueries. Why? How to implement need logic: sum of those subqueries that found something? How to check that? Regards, Vadim Gindin
