                filterClause.Add(new DateRangeQuery
                {
                    Boost = 1.1,
                    Field = new Field("TRANSACTIONDATE"),

                {

                    Size = 10,
                    Scroll="10s",

                Query = new BoolQuery
                    {
                        Must = filters,
                        Filter = filterClause
                        
                    }
