The range query: +air_date:[0401010000 TO 0411162359] is almost certainly causing your problems. It expands further to all terms in the range. Several solutions to this have been discussed earlier, ao. splitting dates into day and time components. Once you approach 1000 days, you'll get the same problem again, so you might want to use a filter for the dates. See DateFilter and the archives on YYYYMMDD.
