Erick,
Thanks for the quick response. The output i showed is on a test instance i
created to simulate this issue. I intentionally tried to create documents with
no values by creating xml nodes with "<field name="fieldName"></field>", but
having values in the other fields in a document.
Are you saying that there is no way have a field with no value?, with text
fields they seem to make sense than for string?.
You are right on fieldName:[* TO *] results, which basically returned all the
documents which included the couple of documents in question.
