Hello, I would like to search for documents that do not have a value for a particular field. I understand org.apache.lucene.search.FieldValueFilter serves the purpose to filter out documents that have/do-not-have a value.
I am just wondering the way to associate this filter with a Query object. I use QueryParser to construct the Query object. Let me illustrate with a sample query. Sample Query : (Author:John OR Author:Harry) AND (-Published_Year:NULL OR Title:Delhi*) In the above query, I just want to use the FieldValueFilter for the criteria *-Published_Year:NULL* Am I missing something basic here? Glad if you can help. Thanks in advance. -- With Thanks and Regards, Ramprakash Ramamoorthy, Chennai, India
