Hello again, I've modified DateFilter to filter out document IDs as suggested. All seems to be running well until I tried a specific test case. All my documents have IDs in the 400,000 range. If I set my lower limit to 5, nothing comes back. After examining the code, I found the issue to be at the following line: TermEnum enumerator = reader.terms(new Term(field, start));
Is there a way to retrieve a set of documents with IDs using a Integer comparison versus a String comparison? If I set "start" to 0, I get everything, but that's not very efficient.
