Thank you for your answer Chris.

What I did was to get all the Documents from the old indexes, and loop
the existingDocuments, then I replaced the "date" field by the same
values but created with LongPoints.
Something like this:
	
for (Document existingDocument : existingDocuments) {
Document doc = createDocument();

doc.add(createStringField("recordId", existingDocument.get("recordId"),
Field.Store.YES));

//Here I create a new LongPoint based on the "date" of the 
//old documents represented by LongField 
doc.add(new
LongPoint("date",Long.valueOf(existingDocument.get("date"))));

indexWriter.updateDocument(new
Term("recordId",existingDocument.get("recordId")), doc);
}

This way my queries are returning the number of hits I expected.
Do you think this is wrong in any way? I don't know if this can be
considered reindex, since I'm not using the original documents to index
but old indexes and if it can cause any problems.

Thanks,
Nuno Oliveira
