Sample query

Age search terms.

   private void addAgeSearchTerm(final BoolQueryBuilder queryBuilder, final Integer minAge, final Integer maxAge) {
            for (int i = 0; i <= 4; i++) {
                queryBuilder.should(new RangeQueryBuilder("age").from(minAge).to(maxAge + i)
                                .boost((ageWeight / (i + 1))));

            }

            for (int i = 0; i <= 3; i++) {
                queryBuilder.should(new RangeQueryBuilder("age").from(minAge - i).to(maxAge)
                                .boost((ageWeight / (i + 1))));
            }
    }
